Typical application circuit
Application Information
When excessive current flows due to output short-circuit or so, ringing occurs because of inductance between power
source line to IC, and may cause bad influences on IC operations. In order to avoid this case, connect a bypass
capacitor across IN terminal and GND terminal of IC. 1μF or higher is recommended.
This application circuit does not guarantee its operation.
When using the circuit with changes to the external circuit constants, make sure to leave an adequate margin for
external compone nts includin g AC/DC characteristics as well as dispersion of the IC.

TSZ22111･15･001 TSZ02201-0E3E0H300370-1-2
21.Feb.2014 Rev.002
Operation Description
BD2202G and BD2206G are high side switch ICs with over-current protection function. The operating voltage range is
from 2.7V to 3.6V and th e current limit value is set to 400mA and 1A respectively.
When an over-current con dition lasts longer than its over-current shutdown time, the s witch turns OFF. The OFF switch
is set to latch mode. The switch set to latch mode returns to normal by toggling EN pin from High to Low to High.
1.Switch On/Off control
VIN terminal and VOUT terminal are con nected to the drain and the sour ce of switch MOSFET respectively. And the
VIN terminal is used also as power source input to internal control circuit.
When the switch is turned on from EN control input, VIN and VOUT are connected by a 150mΩ switch. In normal
condition, the switch is bidirectional. Therefore, when the voltage of VOUT is higher than VIN the current flows from
VOUT to VIN.
In the switch MOSF ET, there is a parasitic diode (body di ode) bet ween drain and source. So, even when the s witch is
off, when voltage of VOUT is higher than VIN, the current flows through th e body diode from VOUT to VIN.
2. Over current detection (OCD)
The over current detection circuit limits current flowing in switch MOSFET when it exceeds its limit threshold. There
are three types of responses against over current. The over current detection circuit is in operation when the power
switch is ON (when EN signal is active).
2-1 When the switch is t urned on while the output is in short-circuit status
When the switch is turned on while the output is in short-circuit status, the switch goes into current limit status
immediately.
2-2 When the output short-circuits while the switch is on
When the output short-circuits or high-current load is connected while the switch is on, very large current flows
until the over current limit circuit reacts. When the current detection and limit circuit works, current limitation is
carried out.
2-3 When the output current increases gradually
When the output current increases gra dually, current limitation d oes not work until the out put current exceeds th e
over current detection val ue. When it exceeds the detection valu e, current limitation is carried out.
3.Over current shutdown
When the over current detection circuit detects an over current, TBLANK timer starts working. W hen the over current
condition disappears before TBLANK2 stage, TBLANK timer is reset. When the over current condition progresses to
more than TBLANK1, the switch is shut off. The OFF switch is set to latch off mode. The latch is reset when EN
terminal is toggled or when UVLO is detected.
4.Under voltage lockout (UVLO)
UVLO keeps the power switch off until VIN voltage exceeds 2.3V (Typ.). Moreover, from a power switch ON situat ion,
if VIN voltage drops to 2.2V (Typ.), the p ower switch is set to OFF. UVLO has a 100mV hysteresis. The under voltage
lock out circuit is in operatio n when power switch is ON (when EN signal is active).
5.Thermal shutdown
When the chip temperature increases to 160°C (Typ.), the thermal shut down circuit works and the power switch is
turned OFF. When the chip temperature falls to 140°C (Typ.), the power switch output returns to normal. This
operation will r epeat itself unti l the causes of the chip tem perat ure rise are removed or until t he power s witch output i s
turned off.
The thermal shutdown circuit is in operation when the power s witch is ON (when EN signal is active).

Operational Notes
(1) Absolute Maximum Ratings
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit
between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such
as adding a fuse, in case the IC is operated over the absolute maximum ratings.
(2) Recommended Operating C onditions
These conditions repres ent a range within which the expect ed char acteristi cs of the IC can be ap proxim ately obtained.
The electrical characteristics are guaranteed under the conditions of each parameter.
(3) Reverse Connection of Power Supply
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power
supply terminals.
(4) Power Supply Lines
Design the PCB layout pattern to provide low impedance ground and supply lines. Separate the ground and supply
lines of the digital and analog blocks to prevent noise in the grou nd and supply lines of the digital block from affecting
the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of
temperature and agi ng on the capacitance va lue when using electrolytic capacitors.
(5) Ground voltage
The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that
no pins are at a voltage below the ground pin at any time, even during transient condition.
(6) Short between Pins and Moun ting Errors
Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong
orientation or if pins are shorted together. Short circuit may be caused by conductive particles caught between the
pins.
(7) Operation under Strong Elect r omagnetic Field
Operating the IC in the presence of a strong electromagneti c field may cause the IC to malfunction.
(8) Testing on Application Boards
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply
should always be turned off completely before connecting or removing it from the test setup during the inspection
process. To prevent damage from static discharge, ground the IC during assembl y and use similar precautions durin g
transport and storage.
(9) Regarding Input Pins of the IC
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them
isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a
parasitic diode or transistor. For example (refer to figure below):
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should
be avoided.

(10)GND Wiring Pattern
When using both small-signal and large-current GND traces, the two ground traces should be routed separately but
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal
ground caused b y large curre nts. Also ensur e that the GN D traces of exter nal components do n ot caus e variati ons on
the GND voltage. The power supply and ground lines must be as short and thick as possible to reduce line
impedance.
(11)External capacitor
When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with
temperature and the decrease in nominal capacitance due to DC bias and others.
(12)Thermal Shutdown Circuit (TSD)
The IC incorporates a built-in thermal shutdown circuit, which is designed to turn off the IC when the internal
temperature of the IC reaches a specif ied value. Do not contin ue to operate the I C after this function is activated. Do
not use the IC in conditions where this function will always be activated.
(13) Thermal Consideration
Use a thermal design that allows for a sufficient margin by taking into account t he permissible po wer dissipation (Pd)
in actual operat ing conditions. Consider Pc that does not exceed Pd in actual operating conditions (Pc≥Pd).
