TLC5940QRHBREP

Overview

The TLC5940QRHBREP is a Texas Instruments LED lighting driver IC featuring 16 constant-current sink outputs. 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 utilizes a boost topology with an output voltage capability of 17 V and functions at a working frequency of 30 MHz. Packaged in a VQFN-32 format, it is designed for industrial temperatures ranging from -40°C to +125°C.

Feature Summary

Integrates internal EEPROM for factory-set dot correction to compensate for LED brightness variations.
Provides grayscale PWM control for precise dimming without external microprocessor controllers.
Includes LED open detection capabilities for diagnostic monitoring.

Applications

LED backlighting systems
Signage displays
Dot matrix display drivers

Procurement Notes

Verify the specific suffix 'EP' indicates the exposed pad thermal enhancement feature on the VQFN-32 package. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the full part number against distributor catalogs to confirm availability and exact packaging options.

Selection Notes

Select this component when 16 individually controllable constant-current sinks are required. The wide operating temperature range suits industrial environments. The integrated EEPROM simplifies calibration by removing the need for external memory. Consider the VQFN-32 package size for space-constrained PCB layouts requiring efficient thermal dissipation.

Part Context

This part belongs to the TLC5940 series of 16-channel LED drivers. It shares core functionality with variants like the TLC5940PWPR but differs in package type. The series is characterized by its ability to drive LEDs with high precision using PWM control and built-in current regulation features.
