The bq24715 is a NVDC‑1 synchronous battery charge controller designed for 2‑ or 3‑cell Li‑ion battery applications. It provides low component count, integrated NMOS ACFET and RBFET drivers, and a programmable SMBus interface for precise voltage and current regulation.
Key features include ultra‑fast 100 µs transient response, ultra‑low 500 µA quiescent current, and high light‑load efficiency (80 % at 20 mA). The device supports 6‑24 V input, multiple switching frequencies (600 kHz, 800 kHz, 1 MHz), and includes extensive safety protections such as over‑current, over‑voltage, and MOSFET short‑circuit detection.
