DIS_LDO_TSHUT

0

0: Enabled

1: Disabled

Disables the Thermal Shutdown for the LDO

regulator. This should be set to 0

0

0: Use JEITA profile

settings below

1: Use OTG_COLD

and OTG_HOT

settings to disable

charge modes

0: 50% of ICHG

1: 100% of ICHG

Fast Charge Current Only

JEITA Warm (45°C-60°C) Temperature Current

Setting

Percentage with respect to ICHG register

DIS_JEITA = 0

Notes:

1. Result for 50% is rounded down

Example: 15% IFCHG at 50% reduction results

in 7% output

2. Result minimum is always 1%

Example: 1% IFCHG setting at 50% reduction

is still 1%
