• AEC-Q100 qualified for automotive reliability
• Integrated key output capability
• Supports line/frame driving modes

Applications

• Automotive instrument clusters
• In-car audio display panels
• Vehicle navigation system interfaces

Procurement Notes

Verify the complete part number including the suffix to ensure correct package and temperature grade. Confirm AEC-Q100 compliance requirements for your specific automotive application. Check datasheet for humidity sensitivity handling procedures during assembly. Ensure power supply voltage stays within the specified 2.7 V to 6 V range for proper operation.

Selection Notes

Select this component when high segment count (up to 445) and automotive reliability are required. The TQFP-100V package suits designs needing extensive I/O connectivity. Compare against BU91510KV-ME2 if fewer segments or different thermal performance are sufficient. Verify interface compatibility with the host microcontroller's 3-Wire protocol.

Part Context

This part belongs to ROHM's multi-function LCD segment driver series tailored for automotive use. It complements other models like BU97530KVT-ME2 but offers distinct packaging and specific automotive certification.
