TLC5946PWPR

Overview

The TLC5946PWPR is a Texas Instruments LED display driver featuring 16 channels with 12-bit PWM grayscale control. It operates within a supply voltage range of 3 V to 5.5 V and supports a maximum power dissipation of 3.958 W. The device provides a low-level output current of 5 mA and a high-level output current of -1 mA, with a maximum supply current of 45 mA. It utilizes an HTSSOP-28 package for surface-mount installation and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

Integrates 12-bit PWM grayscale control for precise brightness management
Includes EEPROM-based dot correction for uniform LED appearance
Provides fault detection capabilities including open and short circuit monitoring

Applications

LED matrix displays
Backlight systems
Signage applications

Procurement Notes

Verify the specific ordering suffix 'PWPR' corresponds to the HTSSOP-28 package and reel packaging configuration. Confirm that the component meets RoHS compliance requirements for the target assembly process. Ensure the selected variant aligns with the required operating temperature range and electrical specifications for the intended design application.

Selection Notes

Select this component when 16-channel constant current drive with 12-bit resolution is required. Consider the HTSSOP-28 package constraints for PCB layout. Evaluate the thermal performance given the 3.958 W power dissipation limit. Verify compatibility with the system's serial interface requirements for data input and latch operations.

Part Context

This part belongs to the TLC5946 series of LED drivers from Texas Instruments. It is designed for applications requiring high-resolution grayscale control and individual channel current regulation. The series supports daisy-chaining multiple devices to expand the number of controllable outputs while maintaining synchronization across the chain.

Replacement Considerations

TLC5946PWR is a pin-compatible alternative in tape-and-reel format. TLC5946PW is available in tube packaging. TLC5946RHBR offers a VQFN-32 package option.
