The Texas Instruments TLC5929DBQ is a 16-channel constant current LED driver designed for applications requiring precise LED control. This device features 7-bit global brightness control, allowing for 128 steps of adjustment.
With a power-supply voltage range of 3.0V to 5.5V and an LED power-supply voltage of up to 10V, the TLC5929DBQ provides flexibility in design. It delivers a constant current capability of up to 50mA per channel (at VCC > 3.6V) with high channel-to-channel accuracy of ±1% typical.
Key features include error flags, fault detection, LED open and short detection, power good indication, and thermal shutdown for robust operation. The device also supports a power-save mode with low current consumption and undervoltage lockout. It is available in a 24-SSOP package, suitable for surface mounting.
This LED driver is ideal for signage and other display applications where consistent and adjustable LED illumination is critical. The 2-ns delayed switching between channels helps minimize inrush current.
