MAX16150 nanoPower Pushbutton On/Off Controller and Battery Freshness Seal General Description Benefits and Features The MAX16150 is an extremely low-power, pushbutton, Low Power on/off controller with a switch debouncer and built-in latch. 20nA (max) Standby Current (ISB) This device accepts a noisy input from a mechanical Debounces Noisy Switches switch and produces a clean, latched output, as well as a 50ms and 2s Debounce Timing Options one-shot interrupt output, in response to a switch closure 8s and 16s Shutdown Timing Periods exceeding the debounce period at PB IN. A switch clo- Latched Output Supplies 20mA Load Current with sure longer than shutdown period at PB IN results in a Less Than 100mV Drop longer one-shot interrupt output. The MAX16150 family One-Shot INT Output on Each Switch Closure has two set of devices, one in which a longer switch 8ms, 32ms, 64ms, and 128ms INT Timing Options closure greater than the shutdown period deasserts the Pushbutton Input Handles up to 60V latched output, and another in which the latched output 15kV HBM ESD Protection stays asserted. See Table 1 for more information. 6-pin SOT23 and 1mm x 1.5mm, 6-bump WLP The MAX16150 operates from a supply range of +1.3V to +5.5V and consumes less than 20nA of supply current to Ordering Information appears at end of data sheet. ensure minimal battery drain in low-power applications, as well as to allow use as a batteryfreshness sea. The ro- bust switch input (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 reg- ulator, or it can serve as a switch to connect the load di- rectly to the power supply when load current is low, provid- ing 20mA of output current with less than 100mV voltage drop. A separate INT output provides a system interrupt whenever a valid pushbutton signal is detected. An asyn- chronous CLR input allows an external signal to force the latched output to the off state. The MAX16150 operates over the -40C to +125C tem- perature range and is available in a 1mm x 1.5mm, 6-bump wafer-level package (WLP) and a 6-pin, thin SOT23 package.
