Maxim Integrated Products introduces the MAX16054, a pushbutton on/off controller with debounce circuitry and 15kV ESD protection. This device features state memory that causes the output state to latch after the switch is released/opened, allowing normally open switches to act as on/off switches. Enabling simpler, lower-cost switches with on/off capability, the MAX16054 is ideal for handheld devices, portable electronics, STBs, portable instrumentation, and white goods.

According to Maxim, the MAX16054 is a highly durable device designed to withstand harsh operating conditions. Its integrated switch-debounce circuitry allows the device to accept a noisy input from a mechanical switch and produce a clean, latched digital output signal. This increases reliability and reduces design time compared to alternate solutions. To further increase reliability, the MAX16054 is rated to withstand up to 15kV of ESD, providing essential protection for applications involving an end-user interface. Moreover, the switch's input features overvoltage clamping diodes that allow the device to handle voltage swings of 25V to ground.

The MAX16054 consumes only 7?A of quiescent current. It is available in a small, 6-pin thin-SOT23 package, and is fully specified over the -40C to +125C automotive temperature range.
