Description
Comment
0 - Not in input current limit
by REG_RST detection
by Watchdog 1 - Force input current limit
detection when VBUS is present
Returns to 0 after input detection
is complete
0 – Disable
by REG_RST 1 – Safety timer slowed by 2X
by Watchdog during input DPM (both V and I) or
JEITA cool, or thermal regulation
0 – Allow Q4 turn on, 1 – Turn off
by REG_RST Q4 with t_{BATFET_DLY} delay time
(REG07[3])
Default: Allow Q4 turn on(0)
by REG_RST
by Watchdog
0 – Set Charge Voltage to 4.1V (
max),
1 – Set Charge Voltage to VREG
by REG_RST
0 – Turn off BATFET immediately
when BATFET_DIS bit is set
1 –Turn off BATFET after
t_{BATFET_DLY} (typ. 10 s) when
BATFET_DIS bit is set
Default: 1
Turn off BATFET after t_{BATFET_DLY}
(typ. 10 s) when BATFET_DIS bit
is set
by REG_RST 0 – Disable BATFET reset function Default: 1
by Watchdog 1 – Enable BATFET reset function Enable BATFET reset function
by REG_RST 00 - Disable function (VINDPM set
by register)
01 - VBAT + 200mV
by REG_RST _{10 - VBAT + 250mV}
11 - VBAT + 300mV
Sets VINDPM to track BAT
voltage. Actual VINDPM is higher
of register value and VBAT +
VDPM_BAT_TRACK
LEGEND: R/W = Read/Write; R = Read only
