The TPS2080, TPS2081, and TPS2082 dual and theTPS2085, TPS2086 and TPS2087 quadpower-distribution switches are intended forapplications where heavy capacitive loads and shortcircuits are likely to be encountered.
The TPS208x devices incorporate 80-m ΩN-channel MOSFET high-side power switches for power-distributionsystems that require multiple power switches in a single package. Each switch is controlled by an independentlogic enable input. Gate drive is provided by an internal charge pump designed to control the power-switch risetimes and fall times to minimize current surges during switching. The charge pump requires no externalcomponents and allows operation from supplies as low as 2.7 V.
When the output load exceeds the current-limit threshold or a short is present, the TPS208x limits the outputcurrent to a safe level by switching into a constant-current mode, pulling the overcurrent ( OCx) logic output low.When continuous heavy overloads and short circuits increase the power dissipation in the switch causing thejunction temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. Recovery from athermal shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures the switchremains off until valid input voltage is present. The TPS208x devices are designed to current limit at 1.0-A load.

The power switch is an N-channel MOSFET with a maximum on-state resistance of 135 m Ω(V
I(IN)
= 5V).Configured as a high-side switch, the power switch prevents current flow from OUTx to IN and IN to OUTx whendisabled. The power switch supplies a minimum of 500 mA per switch.
An internal charge pump supplies power to the driver circuit and provides the necessary voltage to pull the gateof the MOSFET above the source. The charge pump operates from input voltages as low as 2.7V and requiresvery little supply current.
The driver controls the gate voltage of the power switch. To limit large current surges and reduce the associatedelectromagnetic interference (EMI) produced, the driver incorporates circuitry that controls the rise times and falltimes of the output voltage. The rise and fall times are typically in the 2-ms to 4-ms range.
The logic enable disables the power switch and the bias for the charge pump, driver, and other circuitry to reducethe supply current to less than 10 μA when a logic high is present on ENx or a logic low is present on ENx. Alogic low input on ENx or logic high on ENx restores bias to the drive and control circuits and turns the power on.The enable input is compatible with both TTL and CMOS logic levels.
The OCx open drain output is asserted (active low) when an overcurrent or over temperature condition isencountered. The output will remain asserted until the overcurrent or overtemperature condition is removed.
A sense FET monitors the current supplied to the load. The sense FET measures current more efficiently thanconventional resistance methods. When an overload or short circuit is encountered, the current-sense circuitrysends a control signal to the driver. The driver in turn reduces the gate voltage and drives the power FET into itssaturation region, which switches the output into a constant current mode and holds the current constant whilevarying the voltage on the load.
The TPS208x implements a dual thermal trip to allow fully independent operation of the power distributionswitches. In an overcurrent or short-circuit condition the junction temperature rises. When the die temperaturerises to approximately 140 °C, the internal thermal sense circuitry checks to determine which power switch is inan overcurrent condition and turns off that switch, thus isolating the fault without interrupting operation of theadjacent power switch. Hysteresis is built into the thermal sense, and after the device has cooled approximately20 degrees, the switch turns back on. The switch continues to cycle off and on until the fault is removed. The( OCx) open-drain output is asserted (active low) when overtemperature or overcurrent occurs.
A voltage sense circuit monitors the input voltage. When the input voltage is below approximately 2 V, a controlsignal turns off the power switch.

Figure 24. Typical Application
A 0.01- μF to 0.1- μF ceramic bypass capacitor between INx and GND, close to the device, is recommended.Placing a high-value electrolytic capacitor on the output pin(s) is recommended when the output load is heavy.This precaution reduces power-supply transients that may cause ringing on the input. Additionally, bypassing theoutput with a 0.01- μF to 0.1- μF ceramic capacitor improves the immunity of the device to short-circuit transients.
A sense FET is employed to check for overcurrent conditions. Unlike current-sense resistors, sense FETs do notincrease the series resistance of the current path. When an overcurrent condition is detected, the devicemaintains a constant output current and reduces the output voltage accordingly. Complete shutdown occurs onlyif the fault is present long enough to activate thermal limiting.
Three possible overload conditions can occur. In the first condition, the output has been shorted before thedevice is enabled or before V
I(IN)
has been applied (see Figure 6 ). The TPS208x senses the short andimmediately switches into a constant-current output.
In the second condition, a short or an overload occurs while the device is enabled. At the instant the overloadoccurs, very high currents may flow for a short time before the current-limit circuit can react (see Figure 10 andFigure 11 ). After the current-limit circuit has tripped (reached the overcurrent trip threshold) the device switchesinto constant-current mode.
In the third condition, the load has been gradually increased beyond the recommended operating current. Thecurrent is permitted to rise until the current-limit threshold is reached or until the thermal limit of the device isexceeded (see Figure 8 ). The TPS208x is capable of delivering current up to the current-limit threshold withoutdamaging the device. Once the threshold has been reached, the device switches into its constant-current mode.
The OC open-drain output is asserted (active low) when an overcurrent or overtemperature condition isencountered. The output will remain asserted until the overcurrent or overtemperature condition is removed.Connecting a heavy capacitive load to an enabled device can cause momentary false overcurrent reporting fromthe inrush current flowing through the device, charging the downstream capacitor. The TPS208x devices aredesigned to reduce false overcurrent reporting. An internal overcurrent transient filter eliminates the need to useexternal components to remove unwanted pulses. Using low-ESR electrolytic capacitors on the output lowers theinrush current flow through the device during hot-plug events by providing a low impedance energy source,thereby reducing erroneous overcurrent reporting.

Figure 25. Typical Circuit for OC Pin
The low on-resistance on the n-channel MOSFET allows small surface-mount packages, such as SOIC, to passlarge currents. The thermal resistance of these packages is high compared to that of power packages; it is gooddesign practice to check power dissipation and junction temperature. Begin by determining the r
DS(on)
of theN-channel MOSFET relative to the input voltage and operating temperature. As an initial estimate, use thehighest operating ambient temperature of interest and read r
DS(on)
from Figure 18 . Using this value, the powerdissipation per switch can be calculated by:P
D
= r
DS(on)

Multiply this number by the total number of switches being used, to get the total power dissipation coming fromthe N-channel MOSFETs.
Finally, calculate the junction temperature:T

Where:

θJA
= Thermal resistance SOIC = 172 °C/W (for 8 pin), 111 °C/W (for 16 pin)P
D
= Total power dissipation based on number of switches being used.
Compare the calculated junction temperature with the initial estimate. If they do not agree within a few degrees,repeat the calculation, using the calculated value as the new estimate. Two or three iterations are generallysufficient to get a reasonable answer.
Thermal protection prevents damage to the IC when heavy-overload or short-circuit faults are present forextended periods of time. The faults force the TPS208x into constant current mode, which causes the voltageacross the high-side switch to increase; under short-circuit conditions, the voltage across the switch is equal tothe input voltage. The increased dissipation causes the junction temperature to rise to high levels. The protectioncircuit senses the junction temperature of the switch and shuts it off. Hysteresis is built into the thermal sensecircuit, and after the device has cooled approximately 20 degrees, the switch turns back on. The switch continuesto cycle in this manner until the load fault or input power is removed.
The TPS208x implements a dual thermal trip to allow fully independent operation of the power distributionswitches. In an overcurrent or short-circuit condition the junction temperature will rise. Once the die temperaturerises to approximately 140 °C, the internal thermal sense circuitry checks which power switch is in an overcurrentcondition and turns that power switch off, thus isolating the fault without interrupting operation of the adjacentpower switch. Should the die temperature exceed the first thermal trip point of 140 °C and reach 160 °C, bothswitches turn off. The OC open-drain output is asserted (active low) when overtemperature or overcurrentoccurs.

UNDERVOLTAGE LOCKOUT (UVLO)l
GENERIC HOT-PLUG APPLICATIONS (see Figure 26 )
TPS2080, TPS2081, TPS2082 DUALTPS2085, TPS2086, TPS2087 QUAD
SLVS202B – SEPTEMBER 2000 – REVISED OCTOBER 2007
An undervoltage lockout ensures that the power switch is in the off state at power up. Whenever the inputvoltage falls below approximately 2 V, the power switch will be quickly turned off. This facilitates the design ofhot-insertion systems where it is not possible to turn off the power switch before input power is removed. TheUVLO will also keep the switch from being turned on until the power supply has reached at least 2 V, even if theswitch is enabled. Upon reinsertion, the power switch will be turned on with a controlled rise time to reduce EMIand voltage overshoots.
In many applications it may be necessary to remove modules or pc boards while the main unit is still operating.These are considered hot-plug applications. Such implementations require the control of current surges seen bythe main power supply and the card being inserted. The most effective way to control these surges is to limit andslowly ramp the current and voltage being applied to the card, similar to the way in which a power supplynormally turns on. Due to the controlled rise times and fall times of the TPS208x, these devices can be used toprovide a softer start-up to devices being hot-plugged into a powered system. The UVLO feature of the TPS208xalso ensures the switch will be off after the card has been removed, and the switch will be off during the nextinsertion. The UVLO feature insures a soft start with a controlled rise time for every insertion of the card ormodule.
Figure 26. Typical Hot-Plug Implementation
By placing the TPS208x between the V
CC
input and the rest of the circuitry, the input power will reach thesedevices first after insertion. The typical rise time of the switch is approximately 2.5 ms, providing a slow voltageramp at the output of the device. This implementation controls system surge currents and provides ahot-plugging mechanism for any device.
