General 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.
Several threshold voltages are offered to accommodate 5.0V,
3.3V, 3.0V and 2.7V system voltages.
These devices are offered in space saving 3-pin SOT23 and SC70
packages.
