MCP9509 - Resistor-Programmable Temperature Switches

General Description

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.

Key Features

  • Resistor-Programmable Temperature Switch.
  • 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).
