Overview
The TLC5949PWP is a Texas Instruments LED lighting driver IC featuring 16 channels with 12-bit ES-PWM grayscale control. It utilizes a boost topology to drive LEDs, supporting an output current of 45 mA per channel and an output voltage up to 10 V. The device operates on a supply voltage between 3 V and 3.6 V, with a maximum power supply current of 14 mA. It functions within a temperature range of -40°C to +85°C and includes internal GS clock, PWM LED driver capabilities, and thermal shutdown protection.
Feature Summary
- Integrates 16-channel constant-current sinks with 12-bit ES-PWM grayscale control for precise LED brightness regulation.
- Incorporates an internal boost converter topology to manage LED driving requirements efficiently.
- Features built-in thermal shutdown protection to safeguard the device during over-temperature conditions.
Applications
- LED backlighting systems
- General LED illumination circuits
- Portable electronic display drivers
Procurement Notes
Verify the specific package variant, as the PWP suffix denotes HTSSOP-24 packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage specifications align with the 3 V to 3.6 V operational range defined in the datasheet. Check humidity sensitivity levels for proper storage and handling procedures during assembly.
Selection Notes
Select this component when designing LED drivers requiring 16 independent channels with high-resolution grayscale control. The integrated boost topology simplifies circuit design by managing voltage conversion internally. Consider the HTSSOP-24 package for surface-mount applications where space efficiency is critical. Verify that the operating temperature range meets the environmental requirements of the target application.
Part Context
The TLC5949PWP belongs to the TLC5949 series of LED lighting drivers from Texas Instruments. This series is designed for applications requiring multiple LED channels with precise current control. The device integrates essential features such as grayscale PWM and thermal protection, making it suitable for compact LED lighting solutions.
Replacement Considerations
Consult official Texas Instruments documentation for verified substitute part numbers. Cross-referencing should be performed based on pin compatibility, electrical specifications, and package dimensions to ensure functional equivalence without redesigning the host circuit.
