Device Overview

Summary

Microchip Technology’s MCP9509/10 devices are programmable 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 kO pull-up resistor.
