Charge current ceiling and I²C programmability
The BQ24152YFFR delivers a programmable charge current up to 1.25 A for a single Li-Ion or Li-Poly cell — enough for a 1000 mAh cell in under an hour, assuming the thermal budget in the 20-DSBGA package holds. The I²C interface lets the host adjust the charge current, termination voltage, and safety timer on the fly, which is useful for systems that throttle charge rate when the die or ambient temperature climbs.
Supply range and battery termination voltage
The input supply maxes out at 6 V — a standard 5 V USB bus fits, but a 9 V or 12 V adapter needs a buck regulator ahead of this charger or a different IC. The battery regulation voltage tops at 4.44 V, which covers both standard 4.2 V cells and the higher-voltage 4.4 V lithium chemistries used in some portable gear.
Fault protection and temperature range
Over-temperature and over-voltage fault protection are integrated — the charger shuts down before the cell or the IC itself enters a dangerous region.
NRND — design-in warning and sourcing posture
For a new design, evaluate the current TI charger family with similar I²C programmability and single-cell support. For ongoing production, we source this part per RFQ against your quantity; confirm the date code and availability at quote time.
