TLC5927IDBQR

Overview

The TLC5927IDBQR is a Texas Instruments LED lighting driver IC featuring 16 constant-current sink channels in a 24-pin SSOP package. It operates on a 3 V to 5.5 V supply with a 30 MHz clock frequency and supports output voltages up to 17 V. The device delivers a maximum output current of 120 mA, adjustable via an external resistor. It includes integrated protection mechanisms such as thermal shutdown and open/short load detection.

Feature Summary

Provides 16 independent constant-current sink channels for uniform LED brightness control
Integrates diagnostic features including open-load and short-load detection capabilities
Supports high-speed serial data input with a maximum clock frequency of 30 MHz
Includes thermal shutdown protection to prevent damage during over-temperature conditions

Applications

LED display panels requiring precise current regulation
General-purpose LED lighting systems
Signage applications utilizing multiple LED strings
Portable devices with limited power supply constraints

Procurement Notes

Verify the specific suffix 'DBQR' corresponds to the SSOP-24 package and tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the operating temperature range meets your environmental requirements. Cross-reference the manufacturer datasheet for exact pinout definitions and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring 16-channel constant-current sinking with integrated fault detection. It is suitable for applications needing adjustable current levels between 5 mA and 120 mA via a single external resistor. Consider its 3 V to 5.5 V input range for compatibility with standard logic supplies and its thermal protection for robust operation in enclosed spaces.

Part Context

This part belongs to the TLC592x family of LED drivers from Texas Instruments. These devices are designed specifically for LED display and lighting applications, offering flexibility through programmable global current gain. The family provides solutions for managing large numbers of LEDs with consistent brightness and diagnostic feedback.
