MM3688 is a temperature switch IC that senses the IC ambient temperature and switches the IC output from Low to High at the detected temperature (active High). It has a built-in hysteresis circuit and keeps the output switched until the ambient temperature falls to the hysteresis temperature. The detection temperature (TDET) can be selected in 1.0°C steps within a range of 60 to 90°C. The detection temperature accuracy is ±2.0°C. This product achieves an ultra-low current consumption of 0.12 μA typ., which is ideal for mobile devices.
