BQ25751RRVR

Battery Chargers Overview

The BQ25751RRVR is a synchronous buck-boost DC/DC charge controller designed for high-voltage battery applications. It supports input voltages from 4.4V to 55V and delivers up to 10A of output current. The device features an adjustable switching frequency ranging from 200kHz to 600kHz with external clock synchronization options. It includes integrated maximum power point tracking (MPPT) for solar arrays and offers comprehensive protection against overvoltage, undervoltage, and overcurrent conditions.

Battery Chargers Feature Summary

• Synchronous buck-boost topology with NFET drivers for optimized efficiency
• Integrated MPPT functionality to maximize solar array energy harvesting
• I2C interface for programmable control and monitoring
• Adjustable switching frequency with external clock synchronization capability

Battery Chargers Applications

• Fire alarm control panels
• Anesthesia delivery systems
• Battery backup units (BBU)
• Elevator main control panels
• Emergency power supplies

Battery Chargers Procurement Notes

Verify the specific suffix RRVR against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with I2C bus requirements and thermal management needs for the target application environment. Cross-reference the part number with the latest Texas Instruments documentation to confirm availability status and any recent design changes or obsolescence notices prior to final procurement decisions.

Battery Chargers Selection Notes

Select this component for applications requiring wide input voltage ranges and bidirectional power flow capabilities. Consider the 10A current rating and 55V output limit when sizing the system. Evaluate the need for external clock synchronization if electromagnetic interference constraints are strict. Verify that the VQFN-36 package fits within the available PCB footprint and thermal dissipation requirements of the design.

Battery Chargers Part Context

This part belongs to the BQ2575x family of high-voltage battery chargers. It is distinct from evaluation modules like the BQ25751EVM, which are used for testing rather than production. The RRVR suffix indicates a specific surface-mount package configuration suitable for automated assembly processes in industrial and medical equipment manufacturing.
