Details
General DescriptionThe 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.Benefts and Features● Low Supply Current: <5μA (typ) at 3V Over Temperature● Precision Factory-Set VCC Monitoring Threshold for 1.8V, 2.5V, 3.3V, and 5V Supplies● Fixed/Pin-Programmable or Resistor-Adjustable Pushbutton Setup Delay● Up to 2 Reset Outputs and 2 Debounced Pushbutton Inputs● Guaranteed RESET Valid for VCC Down to 0.95V● Active-Low RESET Output (Push-Pull or Open-Drain)● Immune to Short Power-Supply Transients● 0.86mm x 1.27mm 6-Bump WLP Package● -40°C to +125°C Operating Temperature RangeApplications● Smartphones● Tablet PCs● eBook Readers● Portable/Battery-Powered Equipment● Glucose Monitors/Patient Monitors● Portable Instrumentation
