AC adapter to system-switch driver output. Connect directly to the gate of the ACFET P-channel power MOSFET and
the reverse conduction blocking P-channel power MOSFET. Connect both FETs as common-source. Connect the
ACFET drain to the system-load side. The PVCC should be connected to the common-source node to ensure that
the ACDRV 4 driver logic is always active when needed. If needed, an optional capacitor from gate to source of
the ACFET is used to slow down the ON and OFF times. The internal gate drive is asymmetrical, allowing a quick turn-off and slower
turn-on in addition to the internal break-before-make logic with respect to the BATDRV. The output goes into linear
regulation mode when the input sensed current exceeds the ACOC threshold. ACDRV is latched off after ACOP
voltage exceeds 2 V, to protect the charging system from an ACFET-overpower condition.
