RT9811 Datasheet | Richtek

Preliminary Micro-Power Voltage Detectors General Description The RT9811 is .. a micro-power voltage detector with de-glitched manual reset input 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 1.5V to 5V, which covers most digital applications. It Features low supply current of 2.5µA. The RT9811 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. Once VDD recovered up-crossing the threshold level, the reset...
