It uses an I²C interface for host-controlled balancing and monitoring, and integrates fault protection against over-current, over-temperature, and over-voltage conditions. The BQ25887RGER is supplied in a 24-VQFN Exposed Pad package (4x4 mm body). No direct stock-holding claim; availability confirmed per RFQ. ## Fault protection set for pack safety The BQ25887RGER includes over-current, over-temperature, and over-voltage fault protection. Over-voltage protection prevents cell voltage exceeding safe limits during charging; over-current and over-temperature cover load faults and thermal runaway scenarios.","metaTitle":"BQ25887RGER Battery Balancer IC – Texas Instruments PMIC","metaDescription":"Texas Instruments BQ25887RGER battery balancer IC for 2-cell Li-ion packs.
