Typical Performance
Description
Microchip Technology’s MCP9501/2/3/4 family devices
are temperature switches with ±1°C (typical) accurate
factory set output thresholds. These devices are ideal for
high-power supply systems where an overtemperature
protection circuit is needed. These devices do not
require external components, consume 25 µA (typical),
and the factory set thresholds provide simplicity.
In addition, this family of devices provides
user-selectable +2°C and +10°C (typical) switch hyster-
esis, and various output configurations. The MCP9501/2
outputs switch for rising temperatures, while the
MCP9503/4 devices switch for falling temperatures, with
the relative hysteresis at the set thresholds. This family
of devices is also available with an active-high, push-pull
output (MCP9502/4) and an active-low, open-drain
output (MCP9501/3). The push-pull output is ideal for a
microcontroller interface, while the open-drain output
can be used for level shifting, wired-OR configuration or
as a heater on/off switch.
The MCP9501/2/3/4 devices operate from a 2.7V to 5.5V
supply. This family is available with the space-saving
5-lead SOT-23 package.

3.0 PIN DESCRIPTION
The description of the pins is listed in Ta bl e 3 - 1 .
3.1 Ground (GND)
The GND pin is the system ground pin. Pin 2 must be
connected to system ground. Pin 1 can also be
connected to system ground which would provide
better thermal conduction to the die.
3.2 Hysteresis Input (HYST)
This is an input pin which can be connected to V
DD
or
GND to select the output hysteresis. Either +2°C
(HYST = GND) or +10°C (HYST = V
DD
)
of the typical
hysteresis can be selected.
3.3 Power Pin (V
DD)
The operating voltage range, as specified in the “DC
Characteristics” table, is applied to this pin.
3.4 Switch Output (Output)
This output is triggered when the temperature rises or
falls beyond the programmed trip temperature thresh-
old. MCP9501/3 devices require an external pull-up
resistor.

MCP9501/2/3/4
4.0 FUNCTIONAL DESCRIPTION
The MCP9501/2/3/4 temperature switch family
integrates a thermal diode, a comparator and a
factory-selectable resistive network used to set the tem-
perature thresholds. The available output thresholds
range from -35°C to +125°C at 10°C increments. There
is no additional configuration required to operate this
device. The selectable output hysteresis is controlled
using a single input pin. When this pin is connected to
ground, the output hysteresis is +2°C (typical), and when
connected to V
DD
, the output hysteresis is +10°C
(typical). Figure 4-1 shows the functional block diagram.
FIGURE 4-1: Functional Block Diagram.
There are two output configurations for this family: a
push-pull, and an open-drain output with active-high
and active-low assertions. These assertion options are
referred to as Cold and Hot options, primarily due to the
direction of the selected hysteresis. For the Cold
option, temperature has to fall below the threshold for
the output to assert high and deassert low when the
temperature rises above the threshold plus the
hysteresis. For example, for a +65°C threshold and
+2°C (typical) hysteresis, when temperature falls below
+65°C, the output asserts high and deasserts low when
temperature rises above +67°C. For the Hot option, the
opposite is true. When temperature rises above +65°C,
the output asserts low and deasserts high when the
temperature falls below +63°C. Figure 4-2 shows a
graphical description for the Hot and Cold options.
FIGURE 4-2: Output Hysteresis.
The push-pull output is ideal for a microcontroller
interface using an input/output pin or an interrupt input
pin. The open-drain option can be used with multiple
sensors in a wired-OR configuration or as a level
shifter.

4.1 Application Information
The MCP9501/2/3/4 temperature switch family
integrates a temperature sensor and a comparator
circuit, which outputs an alert signal when the factory set
temperature threshold is exceeded. No additional com-
ponent is required for device operation, which provides
simplicity to the system designer. The device output
options provide design flexibility for various applications,
such as overtemperature protection circuit or a
closed-loop temperature control unit. This device can be
interfaced to a closed-loop fan controller network without
the need for a microcontroller.
FIGURE 4-3: Fan Controller Using
MCP9502.
The MCP9501/2/3/4 family provides an open-drain
output, where multiple sensors from multiple PCB
hotspots, can be connected to a single processor I/O
input with a wired-OR configuration. The MCP9501
requires an external pull-up resistor, which can be used
to level shift the alert signal. For example, if the sensors
are powered with 5 V
DD
and the controller or processor
is powered with 3 V
DD
, the external resistor can be
level shifted by connecting 3 V
DD
to the pull-up resistor,
as shown in Figure 4-4.
FIGURE 4-4: MCP9501 Wired-OR Output
Configuration with Level Shift.
4.1.1 LAYOUT CONSIDERATION AND
THERMAL CONSIDERATION
This family of sensors measures temperature by
monitoring the voltage level of a thermal diode located
in the die. A low-impedance thermal path between the
die and the PCB is provided by the pins. Therefore, the
sensor effectively monitors PCB temperature. For
efficient performance, it is recommended to layout the
device as close to the heat source as possible.
When connecting an external resistor to the
MCP9501/3, the current through the pull-up resistor
must be considered to prevent self-heat due to power.
This can be determined using Equation 4-1.
EQUATION 4-1: EFFECT OF
SELF-HEATING

asserts active-low and the maximum I
DD
= 50 µA,

4.1.2 POWER SUPPLY REJECTION
The MCP9501/2/3/4 family does not require any
additional components. However, it is recommended
that a decoupling capacitor of 0.1 µF to 1 µF be used
between the V
DD
and GND pins. A high-frequency
ceramic capacitor is recommended. It is necessary for
the capacitor to be located as close as possible to the
power pins in order to provide effective noise
protection.
FIGURE 4-5: Power Supply Filter Using a
Single Resistor .
For applications where a switching regulator is used to
power the sensor, it is recommended to add a 200
resistor in series to V
DD
to filter out the switcher noise.
It is also recommended to add the series resistor in
applications where a linear regulator is used to
step-down a switching regulator voltage to power the
sensor, as shown in Figure 4-5. For example, if a
linearly regulated 3.3V from a 5V switching regulator is
used to power the sensor, add a 200 series resistor.
The MCP9501/2/3/4 family of sensors is designed to
prevent false output triggers due to high-frequency
power supply or system noise. Figure 4-6 shows the
device performance with a high-frequency signal
added on V
DD
. The output is not triggered due to the
signal added on V
DD
. With some applications, it is
recommended to add a bypass capacitor of 0.1 µF to
1µF.

Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
