Overview

The BQ7692003PWR is a highly integrated battery front-end (BFE) monitoring IC designed for 3-cell to 5-cell lithium-ion and lithium-phosphate battery packs. It provides automated protection for overvoltage, undervoltage, overcurrent, and short-circuit conditions while providing a digital I2C interface for a host microcontroller to monitor cell health.

Why Choose This Part

The IC features two separate ADCs: one dedicated to measuring cell voltages and temperatures, and a second continuous coulomb counter for precise current measurement. It reduces system complexity by integrating low-side N-channel FET drivers and cell balancing FETs directly into a 20-TSSOP package.

Applications

Light Electric Vehicles
Ideal for e-bikes and electric scooters requiring 3S to 5S battery configurations with integrated protection.
Power Tools
Provides high-current discharge monitoring and robust protection for cordless drills and saws.
Uninterruptible Power Supplies
Manages backup battery stacks for small-scale UPS systems with multi-chemistry support.

Getting Started

To evaluate this IC, use the BQ76920EVM evaluation module along with the TI bqStudio software for configuration. The device requires a host MCU to manage the I2C interface and handle the alert interrupt signal for real-time pack monitoring.

Also Consider

BQ7693003DBTR TITexas Instruments - Select this version if your application needs to scale up to 6-10 series cells while maintaining the same architecture.
