The BQ25730 BQ 25730 25730 BQ Charging IC is a next-generation NVDC buck–boost battery charger controller designed for 1–5 cell Li-Ion or Li-Polymer batteries. It supports USB Type-C and Power Delivery (PD) inputs and operates across a wide input voltage range (3.5 V–26 V). This IC offers precise system power-path management, enabling simultaneous system operation and battery charging with high efficiency.
The device communicates via I²C or SMBus, allowing full digital control of charging parameters and real-time monitoring. With integrated MOSFET drivers, high power density, and strong protection mechanisms, it’s ideal for notebooks, portable power systems, and USB-C battery-powered devices.
