概要
Description
BQ24610RGET is Texas Instruments’ standalone Li‑ion/Li‑polymer battery charger with built-in power-path management. It accepts a 5V USB or DC input and provides a complete CC/CV charging profile, with preconditioning for deeply discharged cells. It includes safety features such as input current limit, over‑current/overvoltage protection, thermal monitoring, and charge-status indicators, while allowing the system to operate while the battery is charging via a power-path path. The RGET suffix indicates a RoHS-compliant packaging option for this part. External components typically include an inductor, catch diode, input/output capacitors, and programming resistors to set charge current and regulation voltage (about 4.2V). Applications: mobile devices, USB-powered accessories, and other portable electronics needing a compact, single‑chip charger. For exact electrical characteristics and reference designs, consult the bq24610 data sheet and TI application notes.
Equivalent
Direct one-for-one equivalents for BQ24610RGET aren’t published. The closest TI substitutes are other devices in the BQ2461x family with similar features (single-cell Li‑ion charger with USB input). For cross-vendor equivalents, consider common single-cell Li‑ion charger ICs with similar specs: Microchip MCP73831/MCP73832 and Analog Devices LTC4054/LTC4057. Ensure charge current, input source, safety timers, and packaging match your design.
