Disable input voltage limit

VINLIM[6]

6400 mV

Input voltage limit threshold.

Charge current will be reduced to regulate input

voltage at setpoint when in Charge Mode.

Offset: 4.0V

Range: 4.0V (000_0000) to 16.7V (111_1111)

VINLIM[5]

3200 mV

VINLIM[4]

1600 mV

VINLIM[3]

800 mV

VINLIM[2]

Description

Comment

OTG_DIS_CC

0: Enable

1: Disable

Set 1 to disable the output constant current limit

function in OTG Mode

OTG_CC[6]

64%

The OTG output current limit scaling factor relative to

the hardware programmed ILIM current setting.

(VIN side measured at ISRN and ISRP)

Range: 1% (000_0001) to 100% (110_0100)

Setting 110_0100 to 111_1111 = 100%

Setting 000_0000 to 000_0001 = 1%

OTG_CC[5]

32%

OTG_CC[4]

16%

OTG_CC[3]

OTG_CC[2]

OTG_CC[1]

OTG_CC[0]
