The BQ76925PWR from Texas Instruments is a versatile analog front end (AFE) designed for comprehensive battery monitoring and protection in 3- to 6-series Li-ion and Li-polymer battery packs. It facilitates host controller communication via an I2C interface, enabling accurate measurement of individual cell voltages, pack current, and temperature.
Key features include an analog interface for cell measurement with a level shifter and scaler, a variable gain current sense amplifier, and a switchable thermistor bias output for temperature monitoring. The device also incorporates an overcurrent comparator with an adjustable threshold, integrated cell balancing FETs capable of 50 mA per cell, and support for cell sense-line open wire detection. A 3.3-V regulator is integrated for powering microcontrollers or LEDs.
The BQ76925PWR operates within a supply voltage range of 4.2 V to 26.4 V and exhibits low power consumption, with a typical 40 µA in normal mode and a maximum of 1.5 µA in sleep mode. It is available in a 20-pin TSSOP package, suitable for surface mounting.
This IC is ideal for primary protection in battery packs for applications such as cordless power tools, light electric vehicles, UPS systems, medical equipment, and portable test equipment.
