TLC5926IPWPR

Overview

The TLC5926IPWPR is a 16-bit 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 a maximum output current of 120 mA per channel. The device features a serial interface with a clock frequency up to 30 MHz. It is housed in a 24-pin HTSSOP package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides 16 independent constant-current outputs for LED sinking applications
• Integrates fault detection capabilities including open LED, short-to-ground, and short-to-VLED diagnostics
• Utilizes a standard serial interface for data input and control

Applications

• General LED lighting systems
• Indicator arrays requiring constant current regulation
• Industrial display panels

Procurement Notes

Verify the specific suffix 'G4' against the datasheet to confirm RoHS compliance status and lead-free manufacturing details. Ensure the HTSSOP-24 package dimensions match the target PCB footprint. Confirm that the 120 mA output capability aligns with the connected LED load requirements without exceeding thermal limits.

Selection Notes

Select this component when 16-channel constant-current sinking is required with integrated fault monitoring. The wide operating temperature range suits industrial environments. Verify that the serial interface timing meets the system controller's speed requirements. Consider the thermal dissipation characteristics of the HTSSOP package for high-density layouts.
