Frequently Asked Questions
What is the BQ76925PW used for?
The BQ76925PW is a battery monitor IC designed for 6 to 10 series-connected lithium-ion or LiFePO4 cells. It provides individual cell voltage measurement, passive cell balancing via external FETs, and protection against overvoltage, undervoltage, and overcurrent conditions. It is commonly used in industrial battery packs, power tools, e-bikes, and energy storage systems.
What package and pin count does the BQ76925PW come in?
The BQ76925PW comes in a TSSOP-24 package with 24 pins. The 'PW' suffix in the part number specifically denotes the TSSOP package. This compact footprint makes it suitable for space-constrained BMS PCB designs.
What communication interface does the BQ76925PW support?
The BQ76925PW uses an I2C interface operating at up to 400 kHz (Fast Mode). This allows straightforward integration with microcontrollers for reading cell voltages, configuring protection thresholds, and managing cell balancing commands.
What is the operating temperature range of the BQ76925PW?
The BQ76925PW operates from −40°C to +85°C, making it suitable for industrial-grade applications in environments with wide temperature variation, including outdoor energy storage and automotive-adjacent battery management systems.
What are compatible alternatives to the BQ76925PW?
Compatible alternatives include the BQ76930 (10-cell monitor with integrated protection FET drivers), BQ76940 (15-cell monitor), and ISL94202 from Renesas. For higher integration, the BQ76PL455A supports up to 16 cells with daisy-chain communication. Selection depends on cell count, communication protocol, and BOM cost targets.
