The device has two modes to set the VINDPM threshold.
- Fixed VINDPM threshold. The VINDPM is in default set at 4.5 V (programmable from 3.9 V to 5.4 V).
- VINDPM threshold tracks the battery voltage to
optimize the converter headroom between input and output. When it is enabled in REG07[1:0], the
actual input voltage limit is the
higher of the VINDPM setting in register
and VBAT + offset voltage in VINDPM_BAT_TRACK[1:0]
