TLC6946DBQR Description

Short technical summary and product information.

The TLC6946DBQR from Texas Instruments is a high-performance 16-channel LED driver designed for various lighting applications. This device features 16-bit Enhanced Spectrum Pulse Width Modulation (ES-PWM) grayscale control, providing 65,536 steps for precise brightness adjustment. It supports 32 multiplexing, enabling efficient driving of LED displays.

 

The driver operates with a VCC voltage range of 3 V to 5.5 V and offers 16 constant-current-sink channels, each capable of delivering 0.3 mA to 25 mA with a typical channel-to-channel accuracy of ±1.5%. It includes features like fault detection, LED open detection, and thermal shutdown for enhanced reliability. The device is available in a 24-SSOP package, suitable for surface mount applications.

 

Key electrical characteristics include a typical data transfer rate of 33 MHz and a low knee voltage of 0.3 V. The TLC6946DBQR also incorporates 7-bit global brightness control, offering 128 analog dimming steps. Its operating temperature range is -40°C to 85°C, making it suitable for demanding environments.
