BQ76925RGER Description

Short technical summary and product information.

The BQ76925RGER from Texas Instruments is a versatile battery monitor and balancer IC, specifically engineered for 3 to 6 series lithium-ion or lithium-phosphate battery packs. This device functions as an analog front end, providing essential monitoring capabilities for battery cells.

 

Key electrical specifications include a wide supply voltage range from 4.2V to 26.4V and a typical operating current of 40 µA, with a low sleep mode current of 1.5 µA. It supports cell balancing with up to 50 mA per cell and includes an integrated 3.3V regulator for powering microcontrollers or LEDs. Communication is handled via an I2C interface, and it offers features like open-wire detection and an overcurrent comparator with an adjustable threshold.

 

The BQ76925RGER is housed in a 24-VQFN (4x4 mm) package, suitable for surface mounting. Its operating temperature range is -25°C to 85°C, making it adaptable for various environmental conditions. This IC is designed to alert a host system to potential overcurrent faults and can wake the host upon load connection, enhancing system safety and responsiveness.
