3A charge current and I²C programmability
The 3A max charge current is the headline rating for this charger — it defines the charge time for a single-cell Li-Ion pack and sets the thermal budget for the PCB layout around the DSBGA package. The I²C interface lets the system firmware set the charge current dynamically, which is useful for thermal throttling or supporting different battery capacities in the same design. Supply voltage maximum is 10V, and the battery pack voltage is 3.6V nominal — a typical single-cell Li-Ion termination voltage. The charger supports constant-current charging with programmable current via the I²C bus.
Texas Instruments no longer manufactures this ordering code, and no official successor is listed on the record. The part is available to source against an RFQ through our independent distribution network.
