The TLC5923RHBR from Texas Instruments is a 16-channel constant-current sink LED driver designed for various lighting applications. Each channel offers an adjustable current sink up to 80mA, controlled via a serial data interface with a 30MHz data transfer rate. This driver supports 7-bit dot correction, providing 128 steps for individual channel brightness adjustment, which helps in managing brightness variations between LEDs.
Key electrical features include a supply voltage range of 3.0V to 5.5V and the capability to drive LEDs with a supply voltage up to 17V. The device incorporates error detection features such as LED Open Detection (LOD) and Thermal Error Flag (TEF), enhancing system reliability. Its fast switching output with typical rise/fall times of 10ns is suitable for dynamic lighting effects.
The TLC5923RHBR is available in a 32-pin VQFN (5x5 mm) package and a 32-pin HTSSOP package, both designed for surface mounting. The operating temperature range is -40°C to 85°C, making it suitable for a wide array of environmental conditions. This LED driver is particularly useful for applications requiring precise brightness control and fault monitoring, such as backlighting and general illumination.
With its 16 independent channels and advanced control features, the TLC5923RHBR offers a flexible solution for LED driving tasks. The constant current accuracy of ±1% typical ensures consistent performance across all channels.
