Description

The FM803 is a supervisory device designed to monitor power supply or other system voltage. FM803 generates a reset pulse whenever the voltage being monitored is out of tolerance. Once asserted, the reset pulse is guaranteed to be valid for a minimum of 140ms (256ms typical ). The reset output of FM803 is of active low Open-Drain type and has an internal pull-up resistor
