Typical Performance

Description

Microchip Technology’s MCP9501/2/3/4 family of
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 provide user
selectable 2°C and 10°C (typical) switch hysteresis,
and various output configurations. The MCP9501/2
outputs switch for rising temperatures while the
MCP9503/4 switch for falling temperature, with the
relative hysteresis at the set thresholds. This family of
devices is also available with Active-High Push-Pull
and Active-Low Open-Drain outputs, the MCP9502/4
and the MCP9501/3, respectively. The Push-Pull
output is ideal for a microcontroller interface while the
Open-Drain output ca n be used for le vel shif ting, wired­OR configuration, or as a heater on/off switch.

The MCP9501/2/3/4 operate from 2.7V to 5.5V su ppl y.
This family is available with space saving 5-lead
SOT-23 package.

4.0 FUNCTIONAL DESCRIPTION

The MCP9501/2/3/4 temperature switch family
integrates a thermal diode, a com parato r , and a factory
selectable resistive network used to set the
temperature 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 ou tput hyste resis i s
2°C (typic al) and when conn ected to V
hysteresis is 10°C (typical). Figure 4-1 shows the
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 as se rtio ns . Th es e a ss erti on opti ons are
referred to as Cold and Hot options, pri marily due to the
direction of selected hysteresis. For the Cold option,
temperature has to fall below the threshold for the
output to assert High, and de-assert Low when the
temperature rises above the threshold plus the
hysteresis. For example, a 65°C threshold and 2°C
(typical) hysteresis, wh en temperature falls below 6 5°C
the output asserts High, and the de-asserts 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 de-asserts High when the
temperature falls below 63°C. Figure 4-2 shows a
graphical description for the Hot and Cold options.

MCP9501/2/3/4

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
component 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.

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 ex ternal resi stor to the MC P9501/
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.

The MCP9501/2/3/4 family does not require any

that a decou pling capac itor of 0 .1 µF to 1 µF be us ed
between the V

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 200Ω
resistor in series to VDD 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 swi tching regulato r is
used to power the sensor, add a 200Ω series resistor.

The MCP9501/2/3/4 family of sensors is designed to
prevent false output trigger due to high frequency
power supply or system noise. Figure 4-6 shows the
device performa nce with a high f requency s ignal adde d

DS22268A-page 18 © 2011 Microchip Technology Inc.

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 com mitted to continuously improving the c ode prot ection f eatures of our
products. Attempts to break Microchip’s code protection feature may be a violation of t he Digit al Mill ennium Copyright Act. If such act s
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
