The I²C interface allows a host processor to dynamically adjust output voltages, set charge currents, and read fault flags — useful in portable or battery-backed systems where the load profile changes during operation. ## Parametric highlights for the BOM decision Single-cell Li-Ion/Polymer chemistry support means the charge profile is matched to the cell — no external cell-balancing required for a 1S stack. Built-in fault protection against over-temperature and under-voltage reduces the need for discrete supervisor ICs, saving board space and BOM count.","metaTitle":"TPS65021RHAR PMIC - Texas Instruments Power Management IC","metaDescription":"Texas Instruments TPS65021RHAR Power Management IC for single-cell Li-Ion/Polymer.
