The constant-current profile suits Li-ion chemistry; over-temperature protection shuts down the pass element if the die exceeds the safe limit. For a production BOM that needs a 2-cell Li-ion charger, this part is a current-design-in candidate, not a legacy holdover. ## Package and thermal: 20-HTSSOP with exposed pad The 20-PowerTSSOP (4.40 mm width) includes a thermal pad on the underside. The datasheet's recommended PCB footprint ties the pad to the ground plane — without that thermal via array, the 1.2 A charge current will push the die temperature past the 70°C ambient rating in still air.","metaTitle":"BQ24004PWPRG4 Li-Ion Charger IC, 1.2A Max, 8.4V Pack, Active","metaDescription":"Texas Instruments BQ24004PWPRG4 Li-Ion battery charger IC.
