TLC5948ADBQ

Overview

The TLC5948ADBQ is a 16-channel, 16-bit ES-PWM constant-current LED driver featuring full self-diagnosis capabilities. It supports 7-bit dot correction and 7-bit global brightness control for LED lamps. The device operates within a supply voltage range of 3 V to 5.5 V and delivers up to 60 mA output current per channel. It utilizes a boost topology with an operating frequency of 33 MHz and outputs up to 10 V. Packaged in HTSSOP-24, it functions between -40°C and +85°C.

Feature Summary

Integrates 16-bit ES-PWM dimming with independent dot correction and global brightness control channels.
Provides comprehensive self-diagnosis including open LED detection, short-to-ground detection, and thermal shutdown.
Supports daisy-chainable serial data input for efficient multi-device cascading.

Applications

LED lamp drivers
General LED lighting systems
Display backlighting applications

Procurement Notes

Verify the specific suffix 'ADBQ' corresponds to the HTSSOP-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the component meets the required industrial temperature range specifications for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high-resolution 16-bit PWM dimming alongside precise color uniformity via dot correction. It is suitable for applications needing robust fault detection mechanisms such as open LED monitoring. Consider the HTSSOP-24 package constraints and the need for external boost circuitry if higher voltages are required beyond internal limits.

Part Context

This part belongs to the TLC5948A series of LED drivers from Texas Instruments. It shares functional similarities with other members like the TLC5948ADBQR but differs in packaging. The series is designed for high-performance LED lighting where accurate current control and diagnostic feedback are critical for system reliability and maintenance.
