DATA SHEET AAT4292 Seven-Channel High Side I/O Expander General Description Features TM The AAT4292 SmartSwitch is a member of Skyworks V Range: 1.8V 5.5V IN TM Application Specific Power MOSFET (ASPM ) product 7 Independent Output Channels family. The AAT4292 has seven P-channel MOSFETs 1.1 R per Channel DS(ON) 2 configured for use as a high side microprocessor GPIO User Programmable AS Cwire Interface expander powered from a common supply source. Low Quiescent Current Operating over a 1.8V to 5.5V range, the AAT4292 is 6.3A Operational ideal for portable Li-Ion/Polymer powered products. The 0.1A in shutdown state of each output channel is controlled with a single -40C to +85C Temperature Range GPIO line via the EN/SET pin using Skyworks Simple Available in SC70JW-10 Package 2 Serial Control (AS Cwire) interface. The switch states are controlled by Skyworks Simple Applications 2 Serial Control (AS Cwire) interface which permits ease of Cell Phone Keypad, Backlight And Fashion Lighting control and efficiency of size. The quiescent supply Control current is very low, typically 6.3A. In shutdown mode, I/O Expander the supply current is reduced to less than 1A. Media Players The AAT4292 is offered in a Pb-free, 10-pin SC70JW Multiple Channel Low Power Switching package specified over the -40C to +85C temperature Portable Electronic Devices range.

OUT5 2 P-channel MOSFET drain Channel 5 output pin. OUT6 3 P-channel MOSFET drain Channel 6 output pin. OUT7 4 P-channel MOSFET drain Channel 7 output pin. GND 5 Ground connection. 2 Input control pin using AS Cwire serial interface. The device records rising edges of the clock, and decodes them into 128 states controlling the ON/OFF states of the outputs. See Table 1 and Table 2 for EN/SET 6 output settings. In addition, a logic low forces the device into shutdown mode, reducing the supply cur- rent to less than 1A. This pin should not be left floating. OUT1 7 P-channel MOSFET drain Channel 1 output pin.
