Maxim Integrated Products has introduced the MAX16054, a pushbutton on/off controller having debounce circuitry and 15KV ESD protection. This equipment has state memory that makes the output state to latch after the switch is opened, permitting normally open switches to act as on/off switches. Using simpler, lower-cost switches with on/off capability, the controller fits handheld devices, portable electronics, STBs, portable instrumentation and white goods.

Its high durability property can withstand harsh environments. The device's integrated switch-debounce circuitry permits the device to have a noisy input from a mechanical switch and create a clear, latched digital output signal. This improves reliability and speeds up design time-to-market compared to other solutions. To further heighten reliability, the MAX16054 is made to overcome 15KV of ESD, giving essential protection for applications involving an end-user interface. Moreover, the switch's input has overvoltage clamping diodes that help the device to handle voltage swings of 25V to ground.

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