PIN FUNCTION DESCRIPTION

Pin Mnemonic

Function

1 GND

0 V. Ground reference for all signals.

2 RESET (ADM809) Active Low Logic Output. RESET

remains low while VCC is below the

reset threshold, and remains low for

240 ms (typ) after VCC rises above

the reset threshold

2 RESET (ADM810) Active High Logic Output. RESET

remains high while VCC is below the

reset threshold, and remains high for

240 ms (typ) after VCC rises above

the reset threshold.

3

VCC

Supply voltage being monitored.
