Housed in a 20-lead PowerTSSOP with an exposed thermal pad (20-HTSSOP), the part relies on good PCB thermal management to sustain the 1.2 A charge rate without hitting the over-temperature fault threshold. The input supply ceiling is 10 V, so a 12 V adapter or higher bus requires a step-down stage ahead of this charger. ## Charge current and thermal budget At 1.2 A max charge current, the linear regulator dissipates (Vin - Vbatt) × Icharge as heat. The part is supplied on Tape & Reel (TR) for automated pick-and-place assembly.","metaTitle":"BQ24004PWPR Texas Instruments Li-Ion Charger 2-Cell 1.2A","metaDescription":"Texas Instruments BQ24004PWPR 2-cell Li-Ion linear charger, 1.2A max, 8.4V pack, 20-HTSSOP, active production.
