Function
Input power supply is connected to the P-channel MOSFET
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.
Ground connection.
P-channel MOSFET drain.
P-channel MOSFET drain.
P-channel MOSFET drain.
Not connected.
