Ordering Information

General Description

The RT9816 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. It features low supply current of 3

μA. The

RT9816 performs supervisory function by sending out a

threshold level. This reset signal will last the whole period

the threshold level, the reset signal will be released after

a certain delay time. To pull reset signal low manually,

just pull the manual reset input (MR) below the specified
