It is designed for direct charge-from-USB-port topology with a 6.2 V max supply — enough headroom for a 5 V bus with cable and connector drops. The charger delivers constant-current charging up to 2.2 A max, programmable via an external resistor, making it suitable for cell capacities from a few hundred mAh to several Ah in portable equipment. The battery pack voltage ceiling is 9.2 V, matching two-series Li-ion cells at their 4.2 V/cell termination voltage. ## Fault protection and temperature range On-chip fault protection covers overcurrent, overtemperature, overvoltage, and short-circuit conditions — no external supervisor or window-detector IC is needed for basic safety compliance. ## Package, mounting, and thermal considerations The 24-VFQFN with exposed pad (supplier device package 24-VQFN 4x4 mm) requires a thermal land pattern on the PCB to dissipate heat from the internal power FET during high-current charging. Mounting is surface-mount only — no through-hole variant exists for this package. The tape-and-reel or cut-tape packaging options suit both production reflow and prototype hand-assembly. The base product number is BQ25886; the RGER suffix denotes the 24-VQFN package and reel packaging. Marking verification against TI's factory laser etch is straightforward — the date-code font and format are consistent across TI's VQFN product lines, which aids counterfeit screening at incoming inspection.","metaTitle":"BQ25886RGER Texas Instruments 2-Cell Li-Ion Charger, USB","metaDescription":"BQ25886RGER USB Li-Ion charger IC, 2-cell, 2.2 A max charge, 24-VQFN.
