BQ76925RGER
Explore the BQ76925RGER datasheet for detailed specs on this Li-ion protection IC, offering advanced battery monitor features like voltage/temperature sensing, multi-tier safety protocols, and fault detection for energy storage, power tools, and EV applications.

Product Description

The BQ76925RGER is a robust Li-ion protection IC and battery monitor designed for managing 3-series to 5-series cell configurations. It integrates precise voltage, temperature, and current monitoring with autonomous protection features like overvoltage, undervoltage, overtemperature, and short-circuit detection. Supporting direct connections to up to five cells, the IC operates within a 2.7V to 25V range and functions reliably across -40°C to 85°C. It includes a built-in I2C interface for communication with host controllers, enabling real-time data access and cell balancing control. Widely used in industrial applications such as energy storage systems, e-mobility, and power tools, the BQ76925 battery monitor excels in accuracy and safety but requires careful PCB layout for optimal noise immunity. The BQ76925RGER datasheet details its diagnostics, low-power modes, and fault recovery protocols. While lacking internal current sensing (requires an external shunt), it compensates with programmable protections and scalable designs for diverse battery capacities.
