It accepts an input supply up to 28V, which gives headroom for 5V USB or unregulated wall adapters without an external pre-regulator. The 4.2V battery termination voltage matches standard single-cell Li-Ion chemistry. ## Protection set for safe charging Built-in fault protection covers over-voltage on the input, over-temperature on the die, and short-circuit at the battery output. These are hardwired thresholds — no external supervisor needed. The charger enters thermal regulation if the junction hits the limit, reducing current to keep the die safe. ## Package and footprint for compact designs Housed in a 10-WFDFN with exposed pad (10-WSON, 2x2 mm body), the part is surface-mount and requires a thermal pad on the PCB for heat sinking. The small footprint suits space-constrained portable devices.","metaTitle":"BQ24041DSQT Texas Instruments Li-Ion Charger, 1A Max","metaDescription":"Texas Instruments BQ24041DSQT single-cell Li-Ion/Polymer charger IC.
