bq24630 is a highly integrated switch-mode battery charge controller designed specifically for Lithium Phosphate battery
The bq24630 is a highly integrated, stand‑alone synchronous switch‑mode charger designed for lithium‑phosphate (Li‑FePO4) battery packs. It supports 1‑7 series‑connected cells with a 5 V‑28 V input range and provides precise voltage and current regulation.
Key features include a 300 kHz NMOS‑NMOS synchronous buck converter, dynamic power management, multiple safety protections (over‑voltage, over‑current, thermal shutdown, etc.), and a 24‑pin 4 × 4 mm QFN package. The device is targeted at power tools, portable equipment, PDAs, industrial and medical equipment, and other portable electronics.
