Function

Input power supply is connected to the P-channel MOSFETs

sources. Connect a 1µF capacitor from IN to GND.

P-channel MOSFET drain.

P-channel MOSFET drain.

Input control pin using S2Cwire serial interface. The device

records rising edges of the clock and decodes them into 32

states (8 states for AAT4291) which controls the ON/OFF

states of the MOSFETs. See Table 1 and Table 2 for out-

put settings.
