Overview
The TLC5942PWPG4 is a 16-channel, 12-bit PWM LED driver with 7-bit dot correction in a 28-HTSSOP package. It operates from -40°C to +85°C and supports 3V to 5.5V supply voltage. Each channel provides up to 50mA output current. The device features serial data input for daisy-chaining multiple units.
Feature Summary
- Supports 12-bit PWM dimming for precise brightness control
- Includes 7-bit per-channel dot correction for uniformity
- Enables daisy-chain connection via serial data interface
- Provides fault detection capabilities for open and short circuits
Applications
- LED backlighting systems
- General LED indicator arrays
- Portable electronic displays
Procurement Notes
Verify component authenticity through authorized Texas Instruments channels or certified distributors. Confirm the specific PWPG4 suffix matches project requirements. Check for end-of-life status as some sources indicate discontinuation. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification.
Selection Notes
Select this component when 16 independent LED channels with high-resolution dimming are required. The integrated dot correction simplifies hardware design by reducing external calibration needs. Consider the HTSSOP-28 package constraints for PCB layout. Evaluate power dissipation limits under maximum load conditions to ensure thermal stability within the specified operating temperature range.
Part Context
This part belongs to the Texas Instruments TLC594x family of LED drivers. It shares functional similarities with the TLC5940 but adds internal dot correction registers. The PWPG4 designation indicates a lead-free, green package variant compliant with RoHS standards. It serves as a direct replacement for legacy non-correction LED drivers requiring higher color consistency.
Replacement Considerations
The TLC5942PWP is the non-green package equivalent. Verify pin compatibility if substituting with other TLC594x series members like the TLC5940, noting differences in correction features.
