The TLC5954RTQR from Texas Instruments is a 48-channel, constant-current LED driver designed for applications requiring precise LED control. This linear driver offers individual channel current capabilities of up to 34.9 mA for 32 channels and 24.4 mA for 16 channels, with no external resistor needed for current setting.
Key features include 3-bit maximum current control (8 steps) and 7-bit global brightness control for each color group (128 steps across three groups). The device operates with a supply voltage range of 3.0 V to 3.6 V and supports LED power-supply voltages up to 10 V. It boasts high constant-current accuracy, with channel-to-channel typically within ±1% and device-to-device within ±2%.
Designed for reliability, the TLC5954RTQR includes LED open and short detection, undervoltage lockout, and a power-save mode with low consumption. It supports data transfer rates up to 30 MHz and has a minimum BLANK pulse duration of 40 ns. The operating temperature range is -40°C to +85°C.
This component is housed in a 56-VFQFN exposed pad package (8x8 mm) and is suitable for surface mounting. Its primary application is in signage, providing efficient and flexible LED illumination control.
