Description
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.
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 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. The RT9834 is available in the SC-82 and SOT-143 packa.
