MAX16151 High Voltage Pushbutton On/Off Controller

Analog Devices MAX16151 High Voltage Pushbutton On/Off Controller, featuring a switch debouncer and a latched output, is optimized for controlling system power. The MAX16151 can accept a noisy input from a mechanical switch and produce a clean, latched output. The device produces a one-shot interrupt output in response to a switch closure exceeding the debounce period at PB_IN. The MAX16151 operates from a supply range of +5V to +36V and consumes less than 15μA of supply current. The robust switch input (PB_IN) handles ±60V levels and is ±10kV electrostatic discharge (ESD) protected for use in harsh industrial environments. The 3V regulated latched output can serve as a logic signal to control a pass transistor or voltage regulator. A separate INT output provides a system interrupt whenever a valid pushbutton signal is detected. An asynchronous CLR input allows an external signal to force the latched output to the OFF state.
