PIN FUNCTION DESCRIPTION

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.

3VCC

Supply voltage being monitored.
