RT9834 - Micro-Power Voltage Detector

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.

It provides internally fixed threshold levels with 0.1V per step ranging from 1.2V to 5V, which covers most digital applications.

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.
