• Enables precise brightness control through independent PWM and analog dimming pins with up to 10:1 analog ratio.
• Integrates high-side current sensing with P-channel MOSFET for effective short-circuit protection.
• Provides fault monitoring via open-drain output for overtemperature, overvoltage, and overcurrent conditions.

Applications

• Off-grid street lighting systems requiring robust constant-current regulation.
• Advertisement panels and digital signage utilizing single-string LED arrangements.
• Gaming equipment and illuminated signs needing compact driver solutions.
• Automotive exterior lighting applications compliant with AEC-Q100 standards.

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging configuration, such as Tape and Reel (TR), Cut Tape (CT), or Digi-Reel®, matches your assembly requirements. Confirm that the component meets RoHS3 compliance and holds the necessary automotive qualification if intended for vehicle integration. Cross-reference the manufacturer part number with distributor codes to avoid discrepancies in sourcing.

Selection Notes
