The maximum charge current is 2A — enough to charge a typical 2-cell pack in under two hours, with the charge current programmed via an external resistor. The 16V absolute-maximum input voltage covers common wall adapters and 5V USB inputs with headroom. ## Industrial temperature range and fault protection On-chip fault protection covers over-temperature and over-voltage conditions, reducing the need for external supervisory components. ## 20-VFQFN with exposed thermal pad At 2A charge current the pad keeps the junction temperature within the operating range — layout should follow the recommended footprint in the datasheet. ## Programmable current and timer — design flexibility The charger offers programmable charge current and a safety timer. This lets the designer set the charge rate to match the battery capacity and terminate the charge if the timer expires — useful for unattended charging in portable devices.","metaTitle":"TI BQ24103ARHLTG4 bqSWITCHER Li-Ion Charger IC, 2A, 8.4V","metaDescription":"Texas Instruments BQ24103ARHLTG4 bqSWITCHER Li-Ion/Polymer charger IC. 2A max charge current, 8.4V battery pack voltage, 16V input max.
