The Microchip Technology MCP9509HT-E/OT is a resistor-programmable temperature switch designed for various thermal management applications. It features a wide operating voltage range from 2.7V to 5.5V and a broad operating temperature range of -40°C to 125°C.
This device offers user-selectable hysteresis options of 2°C or 10°C (typical). The output configuration is active-low and open-drain, suitable for direct interfacing with microcontrollers or other logic circuits. The temperature switch threshold is programmable with a single external resistor, providing design flexibility.
The MCP9509HT-E/OT is available in a space-saving SOT-23-5 package, making it ideal for applications where board space is limited. Its typical supply current is low at 30 µA, contributing to power efficiency in battery-operated devices.
Applications include power supply thermal shutdown, temperature alarms, thermostat control, and fan control. The accuracy specifications vary with temperature, with typical accuracy of ±0.5°C at +25°C and +45°C, and ±2°C typical over the full -40°C to +125°C range.
