• Integrates six general-purpose/PWM outputs for LED backlight and button illumination
• Features TTL level input compatibility for direct MCU connection

Display Drivers Applications

• Automotive instrument cluster displays
• Vehicle information system screens
• Center console LCD interfaces
• Door panel control displays

Display Drivers Procurement Notes

Verify the complete part number including the suffix ME2 to ensure correct packaging and specifications. Confirm AEC-Q100 qualification status if functional safety documentation is required for your specific application. Check the latest datasheet for any updates regarding operating conditions or pin assignments before finalizing the design.

Display Drivers Selection Notes

Select this component when designing automotive displays requiring high segment counts up to 216. It is suitable for applications needing direct MCU interfacing via TTL inputs. Consider the VQFP-64 package size constraints and the requirement for external components if higher drive currents are needed beyond the internal capabilities.

Display Drivers Part Context

This part belongs to the BU915xx series of multi-function LCD segment drivers designed specifically for automotive environments. It shares the VQFP-64 form factor and 3-wire interface commonality with other members like the BU91501KV-ME2, but offers distinct segment capacity and duty cycle options tailored for complex dashboard displays.

Display Drivers Replacement Considerations

BU91510KV-M is the base model alias for this component. Verify mechanical footprint compatibility when substituting with other BU915xx series drivers.
