AC adapter detection open drain output. It is pulled HIGH to external pull-up supply rail by external pull-up resistor when
voltage on ACDET pin is between 2.4V and 3.15V, and voltage on VCC is above UVLO and voltage on VCC pin is
275mV above voltage on SRN pin, indicating a valid adapter is present to start charge. If any one of the above
conditions can not meet, it is pulled LOW to GND by internal MOSFET. Connect a 10kΩ pull up resistor from ACOK to
the pull-up supply rail
