ACT2861

30V Buck-Boost Charger with Integrated MOSFETs and OTG

REG 0x1C: JEITA (R/W) (NVM)

Bit

Name

Description

Comment

DIS_LDO_TSHUT

0: Enabled

1: Disabled

Disables the Thermal Shutdown for the LDO

regulator. This should be set to 0

DIS_JEITA

0: Use JEITA profile

settings below

1: Use OTG_COLD and

OTG_HOT settings to

disable charge modes

JEITA_VSETH [2]

000: VTERM

001: VTERM-200mV

010: VTERM-300mV

011: VTERM-400mV

100: VTERM-450mV

101: VTERM-500mV

110: VTERM-600mV

111: VTERM-750mV

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

Setting

DIS_JEITA = 0

JEITA_VSETH[1]

JEITA_VSETH[0]

JEITA_ISETH

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%

JEITA_ISETC[1]

00: Charge Suspend

01: 25% of ICHG

10: 50% of ICHG

11: 100% of ICHG

Fast Charge Current

JEITA Low (0°C-10°C) Temperature Current

Setting

Percentage with respect to ICHG register

DIS_JEITA = 0

Notes:

1. Result for 50% and 25% is rounded down

Example: 15% IFCHG setting at 50% results

in 7% output

2. Result minimum is always 1%

Example: 2% IFCHG setting at 25%

reduction is still 1%
