MAX6854/MAX6855/MAX6856 Pin Description

NAME

FUNCTION

MAX6854/

MAX6856

MAX6855

Active-Low Open-Drain or Push-Pull Reset Output. RESET transitions from high to

low when V drops below the selected reset threshold or MR is pulled low.

—

RESET

RESET remains low for the reset timeout period after V

exceeds the device

reset threshold and MR deasserts. Push-pull RESET outputs are referenced to

. Open-drain RESET outputs require an external pullup resistor.

GND

Ground. Connect all GND inputs to the same potential.

Active-Low Manual Reset Input. Drive MR low to initiate a reset. The reset output

remains asserted while MR is held low and for the reset timeout period after MR

transitions high. Leave MR unconnected or connect to V

if unused. MR is

internally pulled up to V

through 10kΩ.

Supply Voltage. Input for V

a 0.1µF capacitor to GND.
