RT9816

Micro-Power Voltage Detectors with Manual Reset

RT9816
New

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 3μA. The RT9816 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 will be released after a certain delay time. To pull reset signal low manually, just pull the manual reset input (MR) below the specified VIL level. RT9816 is provided in SC-82 package.

Applications
