MAX16169AALTA+T

MAX16169AALTA+T is an extremely low-power, pushbutton, on/off controller with a switch debouncer and built-in latch. This device accepts noisy input from a mechanical switch and produces a clean, latched output, and a one-shot interrupt output, in response to a switch closure exceeding the debounce period at PB_IN/active-low PB_IN. A switch closure longer than the shutdown period at PB_IN/active-low PB_IN results in a longer one-shot interrupt output. The MAX16169 family has two sets of devices, one in which a more extended switch closure greater than the shutdown period deasserts the latched output, and another in which the latched output stays asserted. Applications include portable medical devices, portable instruments, handheld consumer electronics, industrial equipment, internet of things (IoT) devices, disposable low-power electronics, asset tracking devices.

• VCC range from 1.3V to 5.5V, 40nA maximum standby current
• Latched output supplies 200mA load current with less than 30mV drop
• One-shot active-low INT output on each switch closure
• Pushbutton input handles up to ±60V
• ±40kV human-body model (HBM) electrostatic discharge (ESD) protection
• Timing accuracy is ±5% typical at (TA = +25°C)
• Interrupt pulse duration is 32ms typical at (beginning at tDB)
• Active-low INT leakage current is ±1nA typical at (TA = +25°C)
• Operating temperature range from -40°C to +125°C
• 6-pin µDFN package
