The TPS3727 is an ultra-low-power voltage supervisor IC designed for power rail monitoring and system reset control. With a typical supply current of only 1.2µA, it is ideal for battery-powered and energy-sensitive designs. The TPS3727 provides overvoltage and undervoltage detection, with programmable reset delays to ensure reliable startup and fault recovery. Packaged in SOT-23 and WSON options, it is widely used in automotive ECUs, IoT devices, industrial controllers, medical equipment, and consumer electronics. Its wide supply voltage support and high reliability make it a preferred choice for system protection in embedded electronics.
