TLC5926IPWPRG4

Overview

The TLC5926IPWPRG4 is a 16-channel constant-current LED sink driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and supports an operating frequency of 30 MHz. The device delivers up to 120 mA per output and is housed in a 24-pin HTSSOP package. It functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates fault detection capabilities including open LED, short-to-ground, and short-to-VLED diagnostics.
• Provides error flagging for immediate status monitoring of channel integrity.

Applications

• General LED lighting systems
• LED display drivers
• Industrial indicator panels

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current product selection guide to ensure compliance with RoHS standards and lead-free requirements. Confirm that the HTSSOP-24 package matches the intended PCB footprint and thermal management strategy for the target application environment.

Selection Notes

Select this component when a 16-bit serial interface is required for driving multiple LEDs with precise constant-current regulation. Ensure the system design accommodates the 3 V to 5.5 V supply constraints and utilizes the 30 MHz clock speed for data transmission without exceeding the maximum operating temperature limits.

Part Context

This part belongs to the TLC592x series of constant-current LED sink drivers from Texas Instruments. It is designed for applications requiring high reliability and diagnostic features, serving as a direct replacement for standard shift-register-based LED drivers where fault detection is critical.

Replacement Considerations

The datasheet lists TLC5926IPWPR as an alternative part number within the same family. Verify pinout compatibility and electrical specifications before substitution.
