The TLC5940 is a 16-channel, constant-current sink LED driver designed for applications requiring precise LED brightness control. Each of its 16 channels features individually adjustable 4096-step grayscale PWM brightness control and a 64-step constant-current sink dot correction. This dot correction capability is crucial for adjusting brightness variations between LED channels and is storable in integrated EEPROM.
The device operates with a supply voltage (VCC) ranging from 3.0V to 5.5V and can drive LEDs with an output voltage up to 17V. It supports a maximum output current of 60 mA when VCC is below 3.6V and 120 mA when VCC is above 3.6V. The TLC5940 utilizes a serial data interface and boasts a high data transfer rate of 30 MHz, enabling efficient control.
Error detection features include LED Open Detection (LOD) and a Thermal Error Flag (TEF), enhancing system reliability. The operating temperature range for this component is -40°C to 85°C. Its capabilities make it suitable for monocolor, multicolor, and full-color LED displays, signboards, display backlighting, and general high-current LED drive applications.
