Description
●The MAX40002–MAX40005 tiny, single comparators are 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. These comparators are offered in both, a miniature 4-bump wafer-level package (WLP) with a 0.73mm x 0.73mm footprint (as small as two 0402 resistors) and a 5-pin SOT23 package.
●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. These devices have 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). They also feature internal filtering to provide high RF immunity.
●The MAX40002–MAX40003 have open-drain outputs, while the MAX40004–MAX40005 feature push-pull outputs. The MAX40002/MAX40004 have noninverting inputs, while the MAX40003/MAX40005 have inverting inputs (see the _Selector Guide_ for more information).
●These devices also come with an internal reference. The reference voltage is preset at the factory and parts are offered with the following voltage options: 0.2V, 0.5V, or 1.222V (see _Ordering Information_ table).
●These devices are fully specified over -40°C to +125°C automotive temperature range.
