Procurement Notes
Verify the specific manufacturer designation, as NXP Semiconductors is the primary entity associated with this component family. Confirm that the HTSSOP-38 package matches your PCB footprint requirements. Ensure the operating temperature range of -40°C to 85°C meets your environmental specifications. Validate compliance documentation for ROHS and REACH if required for your supply chain.
Selection Notes
Select this component when a high-density solution for controlling multiple LEDs is required. The 24-channel configuration reduces board space compared to single-channel drivers. The linear PWM dimming capability allows for precise brightness control. Consider the 38-HTSSOP package size during layout planning to ensure adequate thermal dissipation and pin clearance.
