EN_IBAT
R/W
0b
IBAT Enable
Enable the IBAT output buffer. In low power mode (REG0x01[7] = 1), IBAT buffer
is always disabled regardless of this bit value.
0b Turn off IBAT buffer to minimize Iq <default at POR>
1b: Turn on IBAT buffer

EN_PROCHOT
_LPWR
R/W
00b
Enable PROCHOT during battery only low power mode
With battery only, enable VSYS in PROCHOT with low power consumption. Do
not enable this function with adapter present. Refer to Section 9.3.9.1 for more
details.
00b: Disable low power PROCHOT <default at POR>
01b: Enable VSYS low power PROCHOT
10b: Reserved
11b: Reserved
4
EN_PSYS
R/W
0b
PSYS Enable
Enable PSYS sensing circuit and output buffer (whole PSYS circuit). In low
power mode (REG0x01[7] = 1), PSYS sensing and buffer are always disabled
regardless of this bit value.
0b: Turn off PSYS buffer to minimize Iq <default at POR>
1b: Turn on PSYS buffer

PSYS_RATIO
R/W
1b
PSYS Gain
Ratio of PSYS output current vs total input and battery power with 10-mΩ sense
resistor.
0b: 0.25 µA/W
1b: 1 µA/W <default at POR>
0
PTM_PINSEL
R/W
0b
Select the ILIM_HIZ pin function
0b: charger enters HIZ mode when pull low the ILIM_HIZ pin. <default at POR>
1b: charger enters PTM when pull low the ILIM_HIZ pin.
