MAX16122–MAX16125

Dual Pushbutton Controllers in

Tiny 6-Bump WLP Package

General Description

Beneﬁts and Features

● Low Supply Current: < 5μA (typ) at 3V Over

The MAX16122–MAX16125 pushbutton controllers with

single-supply monitors monitor one or two pushbuttons and

generate a hard reset signal if the buttons are pushed and

held for a setup delay. These devices make it easy to “hide”

the hard reset function in an existing pushbutton, such as a

soft power switch. The devices operate from 1.6V to 5.5V

and consume a quiescent current of only 5µA at 3V.

Pushbutton Setup Delay

● Up to 2 Reset Outputs and 2 Debounced Pushbutton

The MAX16122–MAX16125 have pin-programmable or

setup delays (depending on part suffix, see Table 1a) or

connect an external resistor from SEL to GND to set the

setup delays (E suffix only, see Table 1b).

The MAX16124/MAX16125 have one manual reset input

(MR), a reset output (RESET), and a soft reset output

(SRESET) which mirrors the state of the input. The

MAX16122/MAX16123 have two identical manual reset

inputs (MR1 and MR2) and one reset output (RESET). A

deglitch block is connected to each input to add a delay to

The devices feature a comparator that monitors the

input supply voltage. A variety of factory-trimmed threshold

options accommodate different supply voltages and

tolerances, eliminating external components. The factory-

set reset thresholds range from 1.58V to 4.63V to monitor

5V, 3.3V, 2.5V, and 1.8V supplies.
