MCP9509/10

Resistor-Programmable Temperature Switches

Description

Features

• Resistor-Programmable Temperature Switch

Microchip Technology’s MCP9509/10 devices are pro-

grammable logic output temperature switches. The

temperature switch threshold can be programmed with

a single external resistor, which provides high design

flexibility and simplicity. In addition, this family of

devices provide user programmable features such as

2°C and 10°C (typical) switch hysteresis and output

structure configuration. The MCP9509 provides an

open drain output, whereas the MCP9510 is offered in

three different user selectable output configurations:

Active-low/Active-high push pull and Active-Low

Open-Drain output with an internal 100 kΩ pull-up

resistor.

• Wide Operating Voltage Range: 2.7V to 5.5V

• Low Supply Current: 30 µA (typical)

• Temperature Switch Accuracy:

- ±0.5°C (typical) at +25°C, +45°C

- ±1°C (typical) 0°C to +70°C

- ±3.5°C (maximum) 0°C to +125°C

- ±4.5°C (maximum) -20°C to +125°C

- ±2°C (typical) -40°C to +125°C

• Sensor Options available:

- Switch for rising temperature: Cold to Hot (H)

- Switch for falling temperature: Hot to Cold (C)

• Output Configurations:

The MCP9509/10 operate from 2.7V to 5.5V. This

family is capable of triggering for temperatures -40°C to

+125°C with high accuracy.

- Open-Drain:

– External Pull-up Resistor: MCP9509

– Internal Pull-up Resistor: MCP9510
