It accepts a supply voltage up to 24 V and includes over-voltage fault protection on the output. ## Charge current and thermal budget The constant-current programming is set with an external resistor; the datasheet gives the formula for the desired current. ## Temperature grade and environment The multi-chemistry support covers Li-ion, Li-Po, and LiFePO4 cells, so the same BOM can serve different pack chemistries by adjusting the charge voltage threshold. ## Package and footprint Housed in a 24-VFQFN with exposed pad (4x4 mm body), the part is surface-mount only. The small footprint saves board area but the thermal pad requires a via-in-pad or a large copper pour on the inner layer to conduct heat away.","metaTitle":"BQ24705RGET Battery Charger IC, 8A, 2-4 Cells, 24-VQFN","metaDescription":"Texas Instruments BQ24705RGET multi-chemistry battery charger IC. 8A max charge current, 2-4 cell support, 24-VQFN package.
