FM803 Datasheet (Fairchild Semiconductor) - 3-Pin C Supervisor Device

FM803, 3-Pin C Supervisor Device

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 ).
