The MAX40004ANS02+ is a nanopower comparator in 4 pin WLP package. It is a tiny, single comparator that is ideal for a wide variety of portable electronics applications such as cell phones, media players and notebooks that have extremely tight board space and power constraints. This device family operates with a supply voltage range from 1.7V to 5.5V (either VCC or external VREF) and consumes only 500nA of supply current. This device has a wide input-voltage range of 0.1V to 5.5V, independent of the supply voltage and maintain high impedance at the inputs even when powered down (VCC or external VREF = 0V). It also features internal filtering to provide high RF immunity. Typical applications include mobile devices, portable medical devices, portable instrumentation, notebook computers and electronic toys.
External reference range from 1.7V to 5.5V
500nA current preserves battery power in applications where comparator is constantly monitoring
