PIN NAME FUNCTION
1 GND Ground
2 RESET
Reset Output. RESET is an active-low open-drain (MAX6467) or push-pull (MAX6468) output. RESET
asserts low when V
CC
drops below the selected threshold and remains low for the V
CC
reset timeout period
after V
CC
rises above the threshold. The RESET one-shot asserts low for a xed MR reset timeout period on
the falling edge of the manual reset input. The open-drain output requires an external pullup resistor
3 MR
Manual Reset Input. Drive MR low to initiate a reset output. MR controls an edge-triggered one-shot that
asserts RESET low for a xed MR timeout period when MR is driven low. Internal timing circuitry ignores
switch close and open bounce to ensure proper one-shot reset timing
4 V
CC
Power-Supply Input. V
CC
provides power to the device and is also a monitored voltage. When V
CC
drops
below the selected threshold, RESET asserts low and remains low for the reset timeout period after V
CC
rises above the threshold. For better noise immunity, bypass V
CC
to GND with a 0.1µF capacitor
