Description

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.

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.
