ACT2861

30V Buck-Boost Charger with Integrated MOSFETs and OTG

REG 0x0C: Charger Control 2 (R/W) (NVM)

Bit

Name

Description

Comment

ILIM_LOW

0: 8.5A or 10A

1: 5.7A

Lower ILIM setting for lower power applications.

If set to 0, then uses FET_ILimit (Register 0x01 Bit 4)

setting. If set to 1, then FET_ILimit should be set to 1

for 5.7A setting.

EN_TERM

0 Converter

continues to

operate:

1: Converter is

disabled when

termination is

reached

The bit determines what to do when charge current

drops below ITERM:

0: Converter stays on and continues to regulate

VBAT output to VTERM Voltage
