Overview
The BQ25758RRVR is an I2C-controlled, bidirectional buck-boost DC/DC controller from Texas Instruments. It supports a wide input voltage operating range of 4.2V to 60V and features synchronous buck-boost topology with N-FET drivers. The device allows adjustable switching frequencies from 200kHz to 600kHz and includes integrated loop compensation with soft start. It offers selectable PFM or forced PWM operation for light load efficiency improvement. The controller provides high accuracy with ±2% output voltage regulation and ±3% output current regulation. It integrates a 16-bit ADC for monitoring voltage, current, and temperature.
Feature Summary
- Bidirectional power flow support for forward and reverse power directions
- Integrated 16-bit ADC for precise voltage, current, and temperature monitoring
- I2C control interface with resistor-programmable options for system optimization
- High safety integration including overvoltage, undervoltage, and thermal shutdown protection
Applications
- USB-PD Extended Power Range (EPR) applications
- Battery management systems requiring bidirectional energy transfer
- Industrial power supplies with wide input voltage ranges
- Energy harvesting systems with variable source voltages
Procurement Notes
Verify the specific suffix RRVR corresponds to the VQFN-EP-36 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering quantity aligns with the manufacturer's standard pack size of 3000 units if purchasing in reels. Check for any recent product change notices that may affect pinout or electrical characteristics.
Selection Notes
Select this component when designing systems requiring bidirectional buck-boost conversion within a 4.2V to 60V range. It is suitable for applications needing precise current and voltage regulation with digital control via I2C. Consider the thermal performance in the VQFN-EP-36 package for high-current designs. Evaluate the need for external synchronization or gate driver supply inputs based on efficiency requirements.
Part Context
This part belongs to the BQ25758 series of power management ICs designed for flexible power delivery applications. It complements other battery management solutions by providing robust DC/DC conversion capabilities. The device is part of Texas Instruments' portfolio for advanced power management in industrial and consumer electronics.
Replacement Considerations
Check for direct substitutes within the BQ25758 family or compatible bidirectional controllers from Texas Instruments. Verify pin compatibility and electrical specifications before substituting with similar parts from other manufacturers.
