It accepts a supply up to 16V, which covers most USB-C PD adapters and 12V wall warts without an extra pre-regulator. The charge current and a safety timer are programmable, and the IC includes over-temperature fault protection. ## 2A charge current and thermal reality At 2A charge current, the power dissipated in the internal MOSFETs and sense resistor heats the die. For a 2-cell (8.4V) pack, the charger regulates the final battery voltage at 8.4V. The constant-current phase delivers up to 2A until the cell voltage reaches the regulation threshold, then the charger switches to constant-voltage until the current tapers.","metaTitle":"BQ24125RHLT Li-Ion Battery Charger IC – Texas Instruments","metaDescription":"Texas Instruments BQ24125RHLT bqSWITCHER™ Li-Ion/Polymer charger, 1-3 cells, 2A max, -40°C to 85°C, 20-VQFN.
