The is a MicroPower Voltage Detector with N-channel open-drain output. The voltage detector supervising the power supply voltage level for microprocessors µP or digital systems. It provides internally fixed threshold levels with 0.1V per step ranging from 1.2 to 5V, which covers most digital applications. It features low supply current of 3µA. It performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. This reset signal will lasts the whole period before VDD recovering. Once VDD recovered upcrossing the threshold level, the reset signal will be released after a certain delay time.
