TLC5946RHBR Description

Short technical summary and product information.

The Texas Instruments TLC5946RHBR is a 16-channel, 12-bit Pulse Width Modulation (PWM) LED driver designed for applications requiring precise LED control. It features 6-bit dot correction for enhanced color accuracy and a constant current sink output capability of up to 40mA per channel.

 

This device operates with a supply voltage range of 3V to 5.5V and supports LED power supply voltages up to 17V. The TLC5946RHBR boasts a channel-to-channel accuracy of ±1% typical and a device-to-device accuracy of ±2% typical. It includes features such as LED open detection, LED short to ground detection, and LED short to VLED detection, contributing to robust system performance.

 

With a 30MHz data transfer rate and a 33MHz grayscale PWM clock, the TLC5946RHBR is suitable for monochrome, multicolor, and full-color LED displays, LED signboards, and display backlighting. It is available in a 32-VQFN (5x5) surface-mount package, operating within an ambient temperature range of -40°C to 85°C.
