The TLC5943RHBR from Texas Instruments is a versatile 16-channel, constant current sink LED driver. It utilizes enhanced spectrum pulse-width modulation (ES-PWM) for 16-bit grayscale control, providing 65,536 steps for precise brightness adjustment. Additionally, a 7-bit global brightness control allows for 128 steps of adjustment across all channels.
This device is designed for applications requiring high-performance LED driving, such as LED signboards and display backlighting. It operates with a supply voltage range of 3.0V to 5.5V and can handle LED power-supply voltages up to 17V. The constant current accuracy is ±1.5% channel-to-channel and ±3% device-to-device.
Key features include LED open detection (LOD) and thermal shutdown (TSD) for enhanced reliability. The TLC5943RHBR supports a 30MHz data transfer rate and operates within an ambient temperature range of -40°C to +85°C. It is housed in a 32-VQFN exposed pad package and is suitable for surface mounting.
Applications include monochrome, multicolor, and full-color LED displays, LED signboards, and display backlighting. The driver's constant current sink output and adjustable brightness control make it ideal for a wide range of lighting solutions.
