MAXIM MAX16150CWT+T

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 PB_IN. A switch closure longer than shutdown period at PB_N (overline) results in a longer one-shot interrupt output. The MAX16150 operates from a supply range of +1.3 V to +5.5 V and consumes less than 20 nA 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 (PB_N (overline)) accepts up to ±60 V levels and is ±15 kV 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 20 mA of output current with less than 100 mV voltage drop. A separate IN (overline) output provides a system interrupt whenever a valid pushbutton signal is detected. An asynchronous CLR (overline) input allows an external signal to force the latched output to the off state. The MAX16150 operates over the -40 ℃ to +125 ℃ temperature range and is available in a 1 mm × 1.5 mm, 6-bump wafer-level package (WLP) and a 6-pin, thin SOT23 package.
