FIELD NAME BIT DEFINITION

AC current sink control

0 – AC sink is enabled when USB is valid supply and V

is below detection threshold

ACSINK

1 – Set [ACSINK, USBSINK] = 11 to force both (AC and USB) current sinks OFF

NOTE: [ACSINK, USBSINK] = 01b and 10b combinations are not recommended as these may lead

to unexpected enabling and disabling of the current sinks.

USB current sink control

0 – USB sink is enabled when AC is valid supply and V

USB

is below detection threshold

USBSINK

1 – Set [ACSINK, USBSINK] = 11 to force both (AC and USB) current sinks OFF

NOTE: [ACSINK, USBSINK] = 01b and 10b combinations are not recommended as these may lead

to unexpected enabling and disabling of the current sinks.
