The RT9801 is a micro-power voltage detector supervising the power supply voltage level for microprocessors (µP) or digital systems.

low supply current of 3µA. Selection of VTH is easily achieved through 3 pins connected to GND, VDD or floating for different threshold voltage settings. Two versions of threshold voltages, 1.5V ~ 4V and 2.5V ~ 5V, which are programmed in factory are offered by customer demands. The RT9801 performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. This reset signal will last the whole period before VDD recovering. Reset signal will.
