MCP9501/2/3/4

Temperature Switch with Selectable Hysteresis

Description

Features

• Factory Set Temperature Switch

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.

• Available Temperature Switch Thresholds:

- T_SET= -35°C,-25°C, -15°C, -5°C, 5°C, 15°C,

25°C, 35°C, 45°C, 55°C, 65°C, 75°C, 85°C,

95°C, 105°C, 115°C, 125°C

• Wide Operating Voltage Range: 2.7V to 5.5V

• Low Supply Current: 25 µA (typical)

• Temperature Switch Accuracy:

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 can be used for level shifting, wired-

OR configuration, or as a heater on/off switch.

- ±1°C (typical)

- ±4°C (maximum) -15°C to +75°C

- ±6°C (maximum) -40°C to +125°C

• Switch Threshold Options (Hot/Cold):

- Rising Temp.: MCP9501/2 (Hot Option)

- Falling Temp.: MCP9503/4 (Cold Option)

• Output Configuration Options:

- Active Low, Open-Drain Output: MCP9501/3

– Uses External Pull-up Resistor

- Active-High, Push-Pull Output: MCP9502/4

• User Selectable Hysteresis: 2°C or 10°C (typical)

• 5-lead SOT-23 package

The MCP9501/2/3/4 operate from 2.7V to 5.5V supply.

This family is available with space saving 5-lead

SOT-23 package.
