MAX16122–MAX16125
Dual Pushbutton Controllers in
Tiny 6-Bump WLP Package
Benefits and Features
General Description
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.
The MAX16122–MAX16125 have pin-programmable or
resistor-adjustable setup delay. Connect the SEL pin to
GND, V
CC
, or leave it unconnected to select the different
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 falling edge with a fixed deglitch period of 20ms (t
DB
).
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.
The MAX16122–MAX16125 are offered in a tiny 0.86mm
x 1.27mm, 6-bump WLP package and are specified over
the automotive temperature range (-40°C to +125°C).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
