NAME
V CC
FUNCTION
Input Supply Voltage, nominally +5V. Bypass with a 0.1μF capacitor to GND.
Low-Line Comparator Output. This CMOS-logic output goes low when V CC falls to 52mV

LOWLINE
above the reset threshold. Use LOWLINE to generate an NMI, initiating an orderly shut-
down routine when V CC is falling. LOWLINE swings between V CC and GND.
Active-Low Reset Output. RESET is triggered and stays low when V CC is below the reset
threshold (or during a watchdog timeout for the MAX801). It remains low 200ms after

RESET
V CC rises above the reset threshold (or 200ms after the watchdog timeout occurs).
RESET has a strong pull-down but a relatively weak pull-up, and can be wire-OR con-
nected to logic gates. Valid for V CC ≥ 1V. RESET swings between V CC and GND.
