Product details

Description

The RT9819 is a micro-power voltage detector supervising the power supply voltage level for www.datasheet4u.com microprocessors (μP) or digital systems.

Features

low supply current of 3μA. The RT9819 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. RT9819 is provided in SC-70-3, SC-82 and SOT-23-3 packages. Features z z z z z z z z z z Internally Fixed Threshold 1.2V to 5V in 0.1V Step High Accuracy ±.
