STMicroelectronics Voltage Detector 2.55V max. 3-Pin SOT-23, STM1061N25WX6F

Voltage Detector ICs provide basic voltage monitoring and reset timing for power-on resets.
The STM1061 low power voltage detector monitors the supply input. When the power supply falls below a specified trip point threshold, the output is forced low and remains asserted as long as the VCC input remains below the threshold voltage plus the hysteresis.
