RT9834 Datasheet (Richtek) - Micro-Power Voltage Detector

RT9834, Micro-Power Voltage Detector

The RT9834 is a micro-power voltage detector with deglitched 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 1.2V to 5V, which covers most digital applications.

RT9834 Features

* low supply current of 3μA. The RT9834 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 upcrossing the threshold level, the reset signal wil
