Analog Devices Nano-Power Pushbutton ON/OFF Controller (EU Version)

Description 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_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 deasserts the latched output, and another in which the latched output stays asserted. 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 (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. Also 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 INT output provides a system interrupt whenever a valid pushbutton signal is detected. An asynchronous 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. The temperature range and is available in a 1mm x 1.5mm, 6-bump wafer-level package (WLP) and a 6-pin, thin SOT23 package.
