AAT4670 Datasheet PDF - Advanced Analogic Technologies

General Description
The AAT4670 SmartSwitch™ is part of the Analogic Tech Application Specific Power MOSFET (ASPM™) line of products. The AAT4670 consists of dual, independent, 1A current limited, slew rate controlled P-channel MOSFET power switches with a dedicated source and drain pin assigned to each switch. The internal circuitry automatically derives power from the higher of the two input power source pins with a low operating quiescent current of 18µA. In shutdown mode, the supply current decreases to less than 1µA. The switches operate with inputs ranging from 2.2V to 5.5V, making them ideal for 2.5V, 3V and 5V systems.
