MCP9501/2/3/4

Temperature Switch with Selectable Hysteresis

Microchip Technology

Microchip Technology’s MCP9501/2/3/4 family of devices are temperature switches with ±1°C (typical) accurate factory set output thresholds.

Product Description

These devices are ideal for high power supply systems where an overtemperature protection circuit is needed. These devices do not require external components, consume 25µA (typical), and the factory set thresholds provide simplicity.

In addition, this family of devices provide user selectable 2°C and 10°C (typical) switch hysteresis, and various output configurations. The MCP9501/2 outputs switch for rising temperatures while the MCP9503/4 switch for falling temperature, with the relative hysteresis at the set thresholds. This family of devices is also available with Active-High Push-Pull and Active-Low Open-Drain outputs, the MCP9502/4 and the MCP9501/3, respectively. The Push-Pull output is ideal for a microcontroller interface while the Open-Drain output can be used for level shifting, wired- OR configuration, or as a heater on/off switch.
