TLC59581RTQR Description

Short technical summary and product information.

The TLC59581RTQR from Texas Instruments is a high-performance 48-channel LED driver designed for demanding applications. It utilizes 16-bit Enhanced Shift-PWM (ES-PWM) technology to provide exceptional dimming control with 512 analog dimming steps.

 

This device supports a sink current of up to 25mA at 5VCC and 20mA at 3.3VCC, with excellent channel-to-channel accuracy of ±1% typical. It features global brightness control (3-bit) and color brightness control (9-bit) for each color group, enabling sophisticated lighting effects.

 

The TLC59581RTQR includes essential features like LED Open Detection (LOD), Thermal Shut Down (TSD), and a pre-charge FET to prevent ghosting. It operates over a wide temperature range of -40°C to 85°C and is housed in a 56-QFN (8x8) surface-mount package.

 

With its robust feature set and precise control capabilities, the TLC59581RTQR is well-suited for applications such as LED signage and general illumination.
