Overview
The BQ25758ARRVR is an I2C-controlled, bidirectional buck-boost DC/DC controller designed for wide voltage range applications. It features synchronous buck-boost architecture with N-FET drivers and supports USB-PD Extended Power Range (EPR) in both forward and reverse power directions. The device allows adjustable input and output voltage regulation from 3.3V to 60V with 20mV steps, and current regulation from 400mA to 20A using external sense resistors. It includes an integrated 16-bit ADC for monitoring voltage, current, and temperature, alongside comprehensive safety protections such as overvoltage, undervoltage, overcurrent, and thermal shutdown.
Feature Summary
- Supports USB-PD Extended Power Range (EPR) for bidirectional power flow
- Integrated 16-bit ADC for precise system monitoring
- High accuracy regulation with ±2% output voltage tolerance
- Comprehensive safety integration including thermal shutdown
Applications
- USB PD Extended Power Range (EPR) chargers
- Bidirectional power conversion systems
- Battery management systems requiring high precision
- Portable devices supporting high-power charging standards
Procurement Notes
Verify the specific suffix ARRVR against the official Texas Instruments datasheet to confirm package type and tape/reel specifications. Ensure compatibility with required I2C addressing and external component values for current sensing. Confirm operating temperature range requirements align with the specified industrial limits before finalizing procurement.
Selection Notes
Select this component when designing systems requiring bidirectional power flow with USB-PD EPR support. It is suitable for applications needing precise voltage and current regulation across a wide input/output range. Consider the VQFN-EP-36 package for thermal performance and board space constraints. Evaluate the need for external synchronization or PFM operation based on efficiency targets.
Part Context
The BQ25758 belongs to the BQ25758A family of power management ICs from Texas Instruments. This series focuses on flexible, high-efficiency charging solutions for modern portable electronics. The ARRVR variant specifically denotes the surface-mount reel packaging configuration, distinguishing it from evaluation modules or other package options within the same functional family.
Replacement Considerations
Consult the official Texas Instruments lifecycle and obsolescence notices for direct substitutes. Verify pin-to-pin compatibility and electrical parameter equivalence if considering alternative manufacturers. No public confirmed substitute part numbers are listed in the provided documentation.
