MAX16150
nanoPower Pushbutton On/Off Controller and Battery Freshness Seal
General Description
The MAX16150A/MAX16150B are extremely low-power, pushbutton, on/off controllers with a switch debouncer and built-in latch. These devices accept a noisy input from a mechanical switch and produce a clean, latched output, as well as a one-shot interrupt output, in response to a switch closure exceeding the debounce period at PB_IN. The MAX16150A de-asserts the latched output when the switch closure period exceeds the shutdown period, while the MAX16150B does not de-assert the latched output in response to switch closure. For the MAX16150B, a longer switch closure results in a longer interrupt signal.
