1 / 16 page 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, VCC, 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 (tDB). 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).
