FUNCTION

Reset Output. RESET is an active-low open-drain (MAX6467) or push-pull (MAX6468) output. RESET

RESET

asserts low when VCC drops below the selected threshold and remains low for the VCC reset timeout period

after VCC rises above the threshold. The RESET one-shot asserts low for a fixed MR reset timeout period on

the falling edge of the manual reset input. The open-drain output requires an external pullup resistor

Manual Reset Input. Drive MR low to initiate a reset output. MR controls an edge-triggered one-shot that

3

MR asserts RESET low for a fixed MR timeout period when MR is driven low. Internal timing circuitry ignores

switch close and open bounce to ensure proper one-shot reset timing

Power-Supply Input. VCC provides power to the device and is also a monitored voltage. When VCC drops

4

VCC below the selected threshold, RESET asserts low and remains low for the reset timeout period after VCC

rises above the threshold. For better noise immunity, bypass VCC to GND with a 0.1µF capacitor
