Charge current and charge timer are programmable via external resistors, so no I2C or GPIO overhead — set the rate with a single passives change. The constant-current/constant-voltage profile is handled internally. ## Thermal and supply budget for the board Maximum supply voltage is 10 V, which covers standard 5 V USB and 9 V wall-adapter rails with margin. The operating ambient range is -40°C to 70°C, suitable for outdoor telecom, industrial handhelds, and automotive cabin-adjacent equipment. At 1.2 A with a 5 V input and 4.2 V battery, expect ~1 W dissipation; a 2-layer board with a solid ground plane under the pad handles it. Built-in over-temperature fault protection shuts down the charger if the die exceeds the safe junction limit — a safeguard against a stalled fan or blocked vent in an enclosure. We source this line through our multi-distributor network — submit an RFQ for a firm delivery commitment.","metaTitle":"BQ24003PWPG4 Texas Instruments Li-Ion Charger IC – 1.2A","metaDescription":"Texas Instruments BQ24003PWPG4 single-cell Li-Ion linear charger, 1.2 A max charge current, -40°C to 70°C, 20-HTSSOP.
