BQ25720 BQ25723 Charger IC | OKSpare Delhi

The BQ25720 and BQ25723 are advanced NVDC (Narrow Voltage DC) buck–boost battery charger controllers designed by Texas Instruments for 1–4 cell Li-Ion or Li-Polymer batteries. These high-efficiency ICs support USB Power Delivery (PD) and Type-C input sources with automatic power path management, ensuring continuous system operation during battery charge or discharge.

Both devices share identical hardware and firmware architecture, differing only in their default register settings. They feature a wide input voltage range (3.5 V–26 V) and dynamically control system power to optimize performance. Integrated MOSFET drivers, intelligent adapter detection, and multiple protection functions make them ideal for notebooks, tablets, and portable embedded systems.
