The TLC5945RHBR from Texas Instruments is a 16-channel, constant-current sink LED driver designed for applications such as LED signboards and display backlighting. Each channel provides individually adjustable 4096-step grayscale PWM brightness control and 64-step constant-current sink for dot correction, ensuring uniform LED brightness across channels.
This device supports a drive capability of 0 mA to 80 mA per channel and operates with a supply voltage range of 3.0 V to 5.5 V, with LED power supply voltages up to 17 V. It features a serial data interface with a 30-MHz data transfer rate and CMOS-level I/O. Error detection capabilities include LED Open Detection (LOD) and Thermal Error Flag (TEF).
The TLC5945RHBR is available in a 32-VQFN (5x5) package with surface mount mounting type. It operates within a temperature range of -40°C to 85°C. The device also includes features like LED Short to Ground Detection and LED Short to VLED Detection.
