7A single-cell charger with I²C programmability
That 7A ceiling puts it in the high-current tier — think tablets, power banks, and industrial handhelds that need to fill a 5000 mAh+ cell in under an hour. The I²C interface means the charge current, termination voltage, and safety timers are set in firmware, not by swapping sense resistors on the board. That saves a BOM line and lets one PCB support multiple battery chemistries with a software change.
Fault protection stack — what it catches
The protection block covers over-current, over-temperature, over-voltage, and reverse-current conditions. Over-voltage on the input rail is the one that usually kills a charger first — a 5V adapter glitching to 6.5V will latch this part off before the FET sees avalanche. Reverse-current protection matters when the battery is connected and the input is absent: the charger blocks the discharge path so the battery doesn't back-feed through the switching converter. Over-temperature shutdown at the die level keeps the part from cooking itself if the thermal pad isn't soldered properly.
The 42-DSBGA package measures 2.8x2.5 mm with a 0.4 mm ball pitch. That is a fine-pitch wafer-level package — the pads are the die bumps, not a substrate interposer. The solder balls are SAC305, so the peak reflow profile tops out at 260°C. Moisture sensitivity level is not listed in this record, but a DSBGA this size typically ships at MSL 1 — bake only if the bag seal is broken and the floor life is exceeded. The thermal pad is the underside of the die; the board layout needs a via-in-pad pattern under the part to pull heat into the inner copper planes.
Maximum supply voltage is 6V, so a standard 5V USB adapter or a 5V regulated rail is the design target. That covers outdoor telecom gear, portable instrumentation, and battery-backed IoT gateways.
That means no last-time-buy clock running, and TI is still taking factory orders for new production. We source this through independent distribution channels and quote firm pricing and lead time against an RFQ for your BOM quantity.
