MAX16122–MAX16125
Dual Pushbutton Controllers in
Tiny 6-Bump WLP Package
General Description
The MAX16122–MAX16125 pushbutton controllers with
single-supply monitors monitor one or two pushbut-
tons 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 cur-
rent of only 5 F A 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 MAX16122–MAX16125 feature a comparator that
monitors the input supply voltage. A variety of factory-
trimmed threshold options accommodate different sup-
ply voltages and tolerances, eliminating external compo-
nents. 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 N C to +125 N C).
