Description
by REG_RST
by Watchdog 0 = 0.5 A
1 = 1.2 A
by REG_RST 0 – Use higher Q1 RDSON when
programmed IINDPM < 700mA
(better accuracy)
1 – Use lower Q1 RDSON always
(better efficiency)

Comment
Default: 1.2 A (1)
Note:
The current limit options listed are
minimum current limit specs.
In boost mode, full FET is always
used and this bit has no effect
Fast Charge Current
Default: 2040mA (100010)
Range: 0 mA (0000000) – 3000
mA (110010)
Note:
I_CHG = 0 mA disables charge.
I_CHG > 3000 mA (110010 clamped
to register value 3000 mA
(110010))
LEGEND: R/W = Read/Write; R = Read only
