TLC5945PWPR Description

Short technical summary and product information.

The TLC5945PWPR from Texas Instruments is a 16-channel, constant-current sink LED driver designed for applications such as LED signboards and display backlighting. Each channel offers individually adjustable 4096-step grayscale PWM brightness control and 64-step constant-current sink for dot correction.

 

This device supports a maximum output current of 80mA per channel and operates with a VCC supply voltage ranging from 3.0V to 5.5V. 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 TLC5945PWPR is available in a 28-HTSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C.

 

Key features include 12-bit grayscale PWM control for smooth brightness adjustments and 6-bit dot correction to manage brightness variations between LED channels. The device also includes LED open detection and thermal error flagging for enhanced reliability.
