NCV78514PA0R2G

Overview

The NCV78514PA0R2G is a single-channel H-bridge LED driver IC from onsemi, designed for automotive applications. It features an integrated input voltage monitor and LED string temperature derating function, allowing operation without a microcontroller. The device supports PWM dimming and includes protection against over-voltage, under-voltage, and thermal faults.

Feature Summary

• Integrates H-bridge topology for direct LED control
• Includes built-in input voltage monitoring capabilities
• Features automatic LED string temperature derating
• Operates independently without external microcontroller

Applications

• Automotive front lighting systems
• LED headlamp modules
• Fog light drivers
• Position lamp circuits

Procurement Notes

Verify the specific suffix 'PA0R2G' matches the required package and tape/reel specifications. Confirm that the component meets AEC-Q100 automotive qualification standards if required by the design. Ensure the ordering quantity aligns with manufacturer packaging constraints to avoid partial reel issues.

Selection Notes

Select this component when a single-channel solution with integrated thermal and voltage management is needed. It is suitable for designs requiring simplified architecture by removing the need for external MCU logic for basic protection and dimming functions. Compare against multi-channel alternatives if higher output counts are necessary.

Part Context

This part belongs to the NCV78514 family of automotive LED drivers. It is distinct from other onsemi series like the NCV789xx which offer multiple channels or different topologies such as buck or boost converters. The NCV78514 specifically targets single-channel H-bridge applications.

Replacement Considerations

Check for NCV78514 variants with different suffixes for package or reel differences. Verify compatibility with existing PCB footprints and thermal requirements before substituting.
