The XC6136C31A9R-G is an ultra-low-power voltage detector manufactured by Torex Semiconductor. It is a member of the supervisory circuits family and its typical supply current is 88nA. This voltage detector is used mainly for brown-out detection, chip enable, reset control, clock monitoring, power-on reset, system power, and signal monitoring at ultra-low power levels. The input voltage range is 1.6V to 5.5V and the output logic is CMOS. Additional features include reset output, output active-low, active-low and hysteresis for accurate detection, high accuracy over temperature range, and pin-compatible SOT-25 package.
