Overview

FM803 3-Pin µC Supervisor Device October 2002 FM803 3-Pin µC Supervisor Device 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.
Features I Automatic reset generation on power-up I M...
