BQ7695202PFBR

Battery Management Overview

The BQ7695202PFBR is a high-accuracy battery monitor and protector designed for lithium-ion, lithium-polymer, and LiFePO4 battery packs consisting of 3 to 16 series cells. It operates within a supply voltage range of 4.7 V to 80 V and features a TQFB-48 package. The device supports I²C, SPI, and HDQ communication interfaces at 400 kHz. It includes an integrated charge pump for high-side NFET driving, dual programmable LDOs, and one-time programmable memory. Operating temperatures span from -40°C to +85°C with a quiescent current of 286 µA.

Battery Management Feature Summary

• Integrates high-precision monitoring with configurable protection for multi-cell battery systems
• Supports autonomous or host-controlled cell balancing via integrated high-side charge pump drivers
• Provides multiple low-power operational modes including deep sleep and shutdown states
• Features on-chip OTP memory for customizable production-line programming

Battery Management Applications

• Electric bicycles and light electric vehicles (LEV)
• Unmanned aerial vehicles (UAV) and drones
• Cordless power tools and garden equipment
• Industrial backup battery units and UPS systems

Battery Management Procurement Notes

Verify the specific suffix '02' against the official datasheet to confirm pinout and functional configuration. Ensure the TQFB-48 package dimensions match the target PCB layout. Confirm that the selected communication interface aligns with the host controller requirements. Check humidity sensitivity levels and storage conditions prior to assembly.

Battery Management Selection Notes

Select this component for applications requiring precise voltage measurement across up to 16 series cells. Consider the 80 V maximum operating voltage when designing for high-capacity battery stacks. Evaluate the need for integrated cell balancing versus external solutions based on system complexity. Verify compatibility with available development kits such as the BQ76952EVM for initial prototyping.

Battery Management Part Context

This part belongs to the BQ76952 family of battery management ICs from Texas Instruments. It serves as a comprehensive solution for monitoring and protecting lithium-based battery chemistries. The device consolidates analog front-end functions with digital control logic, reducing the bill of materials compared to discrete implementations.

Battery Management Replacement Considerations

The BQ76952PFBR is the base variant without the '02' suffix. Verify if the '02' designation indicates a specific pinout or feature set change before substituting.
