Overview
The TLC5942PWP is a Texas Instruments LED display driver featuring 16 constant-current channels. It supports 12-bit PWM dimming and includes 7-bit dot correction stored in EEPROM for uniformity. The device operates on a 3 V to 5.5 V supply with a maximum power current of 60 mA. It utilizes an HTSSOP-28 package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates 12-bit PWM control for precise grayscale dimming across all channels.
- Includes built-in 7-bit EEPROM-based dot correction to ensure consistent LED brightness.
- Provides fault detection capabilities, including open and short circuit monitoring.
Applications
- LED matrix displays
- Backlighting systems
- General LED indicator arrays
Procurement Notes
Verify the specific ordering suffix to confirm package type and tape/reel specifications. Ensure compatibility with the target voltage range and thermal requirements. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement decisions.
Selection Notes
Select this component when 16-channel independent control with high-resolution dimming is required. The integrated dot correction feature simplifies calibration processes compared to non-corrected drivers. Consider the HTSSOP-28 footprint constraints during PCB layout design.
Part Context
This part belongs to the TLC594x series of LED drivers from Texas Instruments. It complements other models like the TLC5940 and TLC5941 by offering enhanced 12-bit resolution and dedicated dot correction hardware, distinguishing it from basic shift-register based drivers.
Replacement Considerations
The TLC5942PWPG4 is a confirmed public substitute part number for the TLC5942PWP. Verify pinout and electrical characteristics match the original design requirements before substitution.
FAQ
What is the bit depth for PWM control?
