TLC5910PZP

Overview

The TLC5910PZP is a 16-channel LED driver IC from Texas Instruments, housed in a 100-pin HTQFP package. It integrates shift registers, data latches, and an on-chip PLL for grayscale generation. The device provides constant current output with 4% accuracy across all channels. Operating voltage ranges from 4.5 V to 5.5 V, with a maximum power dissipation of 4.7 W. It supports SMD/SMT installation and functions within a temperature range of -20°C to +85°C.

Feature Summary

• Integrates on-chip phase-locked loop (PLL) for precise grayscale generation without external timing components.
• Provides constant current drive capability with high channel-to-channel matching accuracy.
• Includes built-in shift registers and data latches for simplified serial data input and storage.

Applications

• High-density LED display systems requiring precise grayscale control
• LED lighting fixtures utilizing PWM dimming techniques
• Electronic signage and large-scale visual displays

Procurement Notes

Verify the specific suffix PZP corresponds to the 100-pin HTQFP package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management solutions account for the specified 4.7 W power dissipation limit under maximum operating conditions.

Selection Notes

Select this component when a high channel count with integrated grayscale generation is required. The on-chip PLL reduces external component count compared to standard drivers. Consider the 100-pin footprint size and thermal requirements for PCB layout planning. Verify compatibility with existing serial interface protocols used in the target system design.

Part Context

This part belongs to the Texas Instruments TLC5910 series of LED drivers. It is designed for applications demanding uniform brightness across multiple channels. The integration of digital control features simplifies system architecture by reducing the need for external microcontrollers or additional logic circuits.

Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Generic cross-references may not match the integrated PLL functionality or constant current accuracy specifications.
