PRODUCTION DATA.
During pre-charge, BATFET works in linear mode or LDO mode (default REG0x00[2] = 1). For 2-4 cell battery, the system is regulated at minimum system voltage in REG0x0D/0C() and the pre-charge current is clamped at 384 mA. For 1 cell battery, the pre-charge to fast charge threshold is 3 V, and the pre-charge current is clamped at 384 mA. However, the BATFET stays in LDO mode operation till battery voltage is above minimum system voltage (~3.6 V). During battery voltage from 3 V to 3.6 V, the fast charge current is clamped at 2 A.
