TLC59281RGET

Overview

The TLC59281RGET is a Texas Instruments LED lighting driver IC featuring 16 constant-current outputs in a VQFN-24 package. It operates on a boost topology with an input voltage range of 3 V to 5.5 V and supports output voltages up to 17 V. The device delivers 35 mA per channel at a maximum clock frequency of 35 MHz. Designed for surface-mount installation, it functions within a temperature range of -40°C to +85°C.

Feature Summary

Provides 16 independent constant-current channels for uniform LED illumination
Integrates internal boost converter to drive high-side loads efficiently
Supports ON/OFF control functionality for precise brightness management
Includes LED open detection capabilities for system reliability monitoring

Applications

General LED lighting systems requiring multi-channel current regulation
Backlighting applications utilizing shift register interface control
Industrial indicator arrays needing robust fault detection features

Procurement Notes

Verify the specific suffix RGET confirms the VQFN-24 package variant during sourcing. Confirm RoHS compliance status matches project requirements. Ensure supply chain partners provide valid traceability documentation. Check moisture sensitivity level handling instructions before assembly. Validate that the manufacturer part number aligns exactly with design specifications.

Selection Notes

Select this component when designing circuits requiring 16-channel constant-current drive with integrated boost conversion. It is suitable for applications needing LED open detection and simple serial interface control. Consider the VQFN-24 footprint constraints and thermal performance limits. Verify compatibility with system operating temperatures ranging from -40°C to +85°C.

Part Context

This device belongs to the TLC59281 series of LED drivers manufactured by Texas Instruments. It shares functional similarities with other members like the TLC59281DBQR but differs in packaging. The series focuses on providing efficient, multi-channel solutions for general lighting and display applications using linear boost topologies.
