It delivers a constant-current charge up to 1.2 A max, with the charge current and safety timer set by external resistors — no I2C or SMBus overhead. ## Charge current and thermal budget at 1.2 A At 1.2 A charge current, the linear regulator drops the input voltage down to the 8.4 V battery voltage. The power dissipated as heat is the input-to-output voltage differential multiplied by the charge current. At a 10 V supply max, that differential can reach 1.6 V, producing nearly 2 W of dissipation — the HTSSOP thermal pad is not optional. ## Active production — no EOL concern No official pin-compatible second source or successor is listed, so the BOM should treat this as a single-sourced line item.","metaTitle":"Texas Instruments BQ24005PWPRG4 Li-Ion Charger IC, 1.2 A Max","metaDescription":"Texas Instruments BQ24005PWPRG4 linear Li-Ion charge manager IC for 2-cell packs, 8.4 V battery voltage, 1.2 A max charge current.
