BQ25638 supports a wide range of input voltage limit (3.8 V – 16.8V). Its POR default VINDPM is set at 4.4V. The charger also supports dynamic VINDPM tracking, which tracks the battery voltage to ensure a sufficient margin between input and battery voltages for proper operation of the buck converter. This function is enabled by default, and can be disabled by clearing the VINDPM_BAT_TRACK register bit to 0. When enabled, the actual input voltage limit will be the higher of the VINDPM register and VINDPM_BAT_TRACK (VBAT + 350 mV offset).
