The TLC5945PWP 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 control for dot correction.
This device features a maximum output current of 80mA per channel and operates with a supply voltage range of 3V to 5.5V. It supports a data transfer rate of up to 30MHz via a serial interface. The TLC5945PWP includes integrated LED open detection and a thermal error flag for enhanced reliability.
Packaged in a 28-HTSSOP, the TLC5945PWP is designed for surface mounting. Its operating temperature range is -40°C to 85°C (TA), making it suitable for various environmental conditions. The driver's topology is based on a shift register, enabling efficient control of the 16 output channels.
