Overview
The TLC5940PWP is a 16-channel constant-current sink LED driver from Texas Instruments, housed in a 28-HTSSOP package. It features individually adjustable 4096-step grayscale PWM brightness control and 64-level DC dimming per channel. The device supports dot correction for uniformity and includes an error flag output for fault detection. Operating on a 3 V to 5.5 V supply, it delivers up to 120 mA per channel with a maximum output voltage of 17 V. Designed for surface-mount installation, it functions within a temperature range of -40°C to +85°C.
Feature Summary
- Provides 16 channels of constant-current sinking with individually adjustable 4096-step grayscale PWM brightness control.
- Integrates dot correction capabilities to ensure consistent LED luminance across all channels.
- Includes an error flag output pin that signals when internal diagnostics detect faults such as open or shorted LEDs.
Applications
- LED backlighting systems
- General-purpose LED display panels
- High-density LED lighting arrays
Procurement Notes
Verify the specific suffix 'PWP' confirms the HTSSOP-28 package and tube packaging format. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision date to guarantee compatibility with your design constraints.
Selection Notes
Select this component when precise per-channel grayscale control is required without external microcontrollers for timing. It is suitable for designs needing high channel density in a compact surface-mount footprint. Consider the thermal dissipation capabilities of the HTSSOP package relative to the total number of active channels and ambient conditions.
Part Context
This part belongs to the TLC5940 family of LED drivers, which are designed for applications requiring high-resolution brightness control. The PWP suffix specifically denotes the plastic heat-sink thin-shrink small-outline package variant. It serves as a foundational component for scalable LED matrix architectures where individual pixel addressing is necessary.
Replacement Considerations
Direct substitutes include the TLC5940PWPR (reel version) and TLC5940QPWPREP (automotive grade). Verify pinout compatibility and electrical parameters before swapping. The TLC5941 offers similar functionality but lacks the grayscale PWM feature.
