Hardware detection pin (open drain). 300 kΩ internal pull-down resistor. V
referred.
Standby mode selection pin. Active HIGH. Terminates the detection and resets
the device.
Output enable for DETECT output. Active LOW.
SW detection output: High when Charger detected. Pulled high or low through
internal weak pull-up to 1V8V and weak pull-down.
Detection method selection input: low for dedicated method, high for current sink
method.
Hardware selection for detection method. Active only if V
Dedicated method is selected if driven low, current sink method if driven high.
