Device Structure

Monolithic charger IC with advanced safety features and an exposed-pad QFN package for improved thermal performance. Integrated protections and programmable charging parameters mean no external controllers are necessary.

Performance Characteristics

Highly adjustable charging current.

Consistent performance across a wide temperature range.

Reliability through built-in overcurrent and overtemperature protections.

Wide input voltage range up to 60V provides flexibility for various system powers.

Application Environments

Battery management systems for consumer devices, industrial hardware, portable instruments, robotics, backup power solutions, power tools, and medical devices.

Selection Guidelines

Best for designers needing flexible, programmable multi-chemistry charging solutions with up to 6 cells in series and a high supply voltage. Surface-mount 28-QFN package suits compact circuit layouts. Ensure your battery chemistry and cell configuration are within the supported range. Evaluate the required charge current and ensure it matches programmable parameters.

Usage Considerations

Observe recommended thermal management due to high-power processes and QFN package. Consider PCB layout for optimal heat dissipation. Ensure all programmable settings (current, cell count) are correctly configured for your battery type. Follow ESD precautions during handling. Confirm all system voltages remain under 60V max.

Potential Equivalent/Replacement Models

Other Analog Devices charger ICs like LTC4015 or LTC4012 may be considered depending on the application’s power and chemistry requirements. Some Texas Instruments bq246xx or Maxim Integrated MAX1737 series may partially overlap, but always confirm pin compatibility and specifications.
