The AAT4290 and AAT4291 SmartSwitch™ products are members of AnalogicTech's Application Specific Power MOSFET™ (ASPM™) product family with five and three P-channel MOSFETs, respectively, configured for use as a microprocessor I/O expander. Having independent drain outputs and a common source input, they operate with an input voltage ranging from 1.8V to 5.5V, making them ideal for 2.5V, 3.3V, or 5V systems, as well as systems powered by Li-Ion batteries. Each switch features a 500ns turn-on time. The switch states are controlled by an S²Cwire interface which permits ease of control and efficiency of size. The quiescent supply current is very low, typically 4.5µA. In shutdown mode, the supply current is reduced to less than 1µA. The AAT4290 and AAT4291 are offered in an 8-pin SC70JW package specified over the -40 to +85°C temperature range.
