Richtek RT9818G-33GVL

电压检测器3.3V1

Overview

The RT9818G-30GVL 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.
