FM809/810 3-Pin µC Supervisor Circuits 4 www.fairchildsemi.com FM809/810 Rev. G Pin Descriptions * with overbar, FM809 (RESET); without, FM810 (RESET). Circuit Timing (e.g.: FM809) When operating properly with 5V in (for example), VOUT will also be about 5V. When VIN starts to fall, VOUT will follow it down as shown. When V IN drops below V TH, V OUT drops to ground ("issues a RESET") and stays there unless V IN also falls below its minimum operating voltage, approx. 1V. At this point, the supervisor loses control, and its output may rise, only to again follow V IN down to the ground. When V IN begins to rise, V OUT follows it until 1.0V or so is reached, whereupon the device regains control, V OUT is pulled to ground, etc. When V IN rises above VTH, VOUT comes out of RESET 140 ms later. If it is required that a lower value than GND + 1.0V is needed on RESET signal during VCC ≤ 1V, a 100K resistor may be used on the device output (to GND for the FM809, to V CC f or the FM810). Pin Number Name Function

1 GND GROUND

2 RESET* RESET (RESET) remains LOW (HIGH) while V CC is below V TH,

and for at least 140ms after VCC rises above VTH. 3V CC VTH GND VTH GND INPUT OUTPUT 140ms
