It integrates over-temperature and over-voltage fault protection, reducing the need for external supervisory components in portable designs. ## 1.5 A charge current — charge-time floor The 1.5 A maximum charge current sets the minimum charge time for a given battery capacity. For a 1500 mAh cell, a full constant-current charge at 1 A takes roughly 1.5 hours, not counting the constant-voltage taper. Charge current and timer are programmable via I²C, so the same BOM can support different cell sizes by adjusting the firmware settings. ## 20-DSBGA — layout and procurement reality The 20-DSBGA package (0.4 mm pitch, 0.5 mm ball diameter) requires a controlled-impedance PCB with micro-via support and a solder-mask-defined pad. Not a hand-solderable part — plan for X-ray inspection on the assembly line. The BQ24156YFFT carries an Obsolete lifecycle status. Available inventory is limited to independent-distribution stock and surplus from prior production runs.
