Maxim Integrated MAX16151 High Voltage Pushbutton On/Off Controller

Maxim Integrated 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 can also produce 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 to ensure minimal battery current in low-power applications. 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.

The Maxim Integrated MAX16151 Pushbutton On/Off Controller is available in a 6-bump Wafer-Level Package (WLP) and a 6-pin thin SOT23 package. the device operates over the -40°C to +125°C temperature range.
