It delivers a constant charge current up to 1.2 A max, making it suitable for portable equipment and backup battery applications where a simple, low-noise charging solution is needed. ## Temperature range and package constraints Operating temperature spans -40°C to 70°C — the 70°C ceiling limits use to indoor or ventilated enclosures; derating above 50°C ambient will reduce the charge current. The 20-HTSSOP package with an exposed thermal pad requires a solid copper pour on the PCB for heat sinking; without it the thermal shutdown may trip before reaching the rated current. ## Active production — no end-of-life concern Sourced through our distribution channel against your BOM quantity — current pricing and lead time confirmed at quote time. ## Programmable current and timer Programmable features include charge current and charge timer, allowing the designer to set the fast-charge rate and safety timeout with external resistors. The constant-current charging profile is a linear regulator topology — no switching noise, but thermal dissipation at 1.2 A with an 8.4 V pack and 10 V supply can exceed 2 W, so the thermal pad layout is critical.","metaTitle":"BQ24004PWPG4 Texas Instruments 2-Cell Li-Ion Charger IC","metaDescription":"Active-production BQ24004PWPG4: 2-cell Li-ion linear charger, 1.2 A max, 8.4 V pack, -40°C to 70°C, 20-HTSSOP.
