Product details

Description

The RT9817 is a micro-power voltage detector with deglitched manual reset input supervising the power www.datasheet4u.com supply voltage level for microprocessors (μP) or digital systems.

Features

low supply current of 3μA. The RT9817 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. RT9817 is provided in SC-82 and SOT-143 packages. Fea.
