OTG_VBAT_CUTOFF[2]

000: VBAT_LOW

001: VBAT_LOW -0.2V

010: VBAT_LOW -0.4V

011: VBAT_LOW -0.6V

100: VBAT_LOW -0.8V

101: VBAT_LOW -1.0V

110: VBAT_LOW -1.2V

111: VBAT_LOW -1.4V

Battery Cut Off threshold for OTG mode to operate.

Referenced from VBAT_LOW level.

OTG_VBAT_CUTOFF[1]

OTG_VBAT_CUTOFF[0]

EN_OTG_nCHG

0: Disable

1: Enable

If EN_OTG_nCHG bit is 1, the IC pulls the nCHG pin

low in OTG mode to indicate the converter is running

in OTG.

If OTG is disabled for any reason, such as VIN Fault

or VBAT Cuttoff level, etc, nCHG goes high.

If set to 0, nCHG is always HIZ in OTG Mode.

OTG_CORD_COMP[1]

00: Disable

01: 100mV

10: 200mV

11: 300mV

OTG Cord Compensation at 2.4A Load with 10m

Ω

resistor

OTG_CORD_COMP[0]

OTG_EN_DLY[1]

00: 0ms

01: 200ms

10: 500ms

11: 1s

The delay before enabling the OTG output from the

nOTG pin or OTG register bit.
