nanoPower Pushbutton On/Off Controller and Battery Freshness Seal

The MAX16150 is a Pushbutton On/Off Controller with a Switch De-Bouncer and Built-In Latch

Please check latest availability status for a specific part variant.


The MAX16150 is an extremely low-power, pushbutton, on/off controller with a switch debouncer and built-in latch. This device accepts a noisy input from a mechanical switch and produces a clean, latched output, as well as a one-shot interrupt output, in response to a switch closure exceeding the debounce period at active-low PB_IN. A switch closure longer than shutdown period at active-low PB_IN results in a longer one-shot interrupt output. The MAX16150 family has two set of devices, one in which a longer switch closure greater than the shutdown period de-asserts the latched output, and another in which the latched output stays asserted. See Table 1 for more information.

The MAX16150 operates from a supply range of +1.3V to +5.5V and consumes less than 20nA of supply current to ensure minimal battery drain in low-power applications, as well as to allow use as a battery "freshness seal". The robust switch input (active-low PB_IN) accepts up to ±60V levels and is ±15kV ESD-protected for use in harsh environments. The latched output can serve as a logic signal to control a regulator, or it can serve as a switch to connect the load directly to the power supply when load current is low, providing 20mA of output current with less than 100mV voltage drop. A separate active-low INT output provides a system interrupt whenever a valid pushbutton signal is detected. An asynchronous active-low CLR input allows an external signal to force the latched output to the off state.

The MAX16150 operates over the -40°C to +125°C temperature range and is available in a 1mm x 1.5mm, 6-bump wafer-level package (WLP) and a 6-pin thin SOT23 package.
