Procurement Notes
Verify the exact part number suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage requirements and thermal management needs. Cross-reference RoHS status and moisture sensitivity levels as required by assembly processes. Confirm availability through authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when 16-channel linear LED driving is required with integrated fault detection. Consider the HTSSOP-24 package for space-constrained designs. Evaluate the 60 mA output current capability against specific LED forward current requirements. Ensure the operating temperature range meets environmental constraints. Compare with alternative drivers if higher current or different interface protocols are needed.
Part Context
The TLC5948PWP belongs to the TLC594x series of LED drivers from Texas Instruments. This family offers multi-channel solutions for various LED applications. The PWP suffix indicates a specific plastic package variant. It complements other TI LED drivers by providing a balance of channel count and diagnostic features suitable for mid-complexity displays.
Replacement Considerations
Publicly confirmed substitutes include the TLC5947PWP (12-channel) or TLC5940PWPR (16-channel, different interface). Verify pinout compatibility and electrical parameters before substitution. Consult Texas Instruments datasheets for detailed cross-reference information.
