ET9823A

일반 설명

The ET9823A is a micro-power voltage detector IC used to monitor the multiple power supplies in microprocessor or logic system. It has high-accuracy, low current consumption and adjustable delay. It performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a present threshold level, and sending out another power detect signal whenever the VCC1, VCC2, or VCC3 power off. Once supplies recovered the threshold level, the reset and power detect signal will be released after a certain delay time controlled by external capacitor.
