It handles a single cell and delivers up to 5 A charge current from a supply voltage up to 14 V. ## 5 A charge current — thermal and layout considerations The 5 A max charge current is the headline rating that drives the charging speed. The I²C interface allows the host to program the charge current, termination voltage, and input current limit, so the same PCB can support different battery chemistries and capacities without a hardware change. ## Fault protection and interface Built-in over-current and over-temperature protection reduce the need for external supervisory circuits. The USB interface supports direct connection to a USB VBUS line; the I²C bus gives the system controller visibility into charge status, fault flags, and battery voltage. The base product number BQ25890 covers the family; the RTWT suffix identifies the 24-WQFN package and tape-and-reel delivery.","metaTitle":"BQ25890RTWT MaxCharge™ Battery Charger IC, 5 A, 14 V","metaDescription":"TI BQ25890RTWT single-cell Li-Ion/Polymer charger IC. 5 A max charge current, I²C/USB interface, -40°C to 85°C.
