The Texas Instruments TLC59281DBQ is a 16-channel, constant-current sink LED driver designed for applications requiring precise LED current control. Each of the 16 channels can be individually turned on or off via serial data input, allowing for flexible control.
The device offers a constant-current capability of 35mA per channel, with a channel-to-channel accuracy of ±1% and device-to-device accuracy of ±1%. It supports a high data transfer rate of 35MHz and features a fast 10ns constant-current switching transient time. The operating supply voltage for the LEDs can be up to 17V, while the logic supply voltage (VCC) ranges from 3.0V to 5.5V.
Packaged in a 24-SSOP, the TLC59281DBQ is suitable for surface mount applications. Its operating temperature range is -40°C to +85°C, making it robust for various environmental conditions. This LED driver is ideal for use in LED video displays, message boards, and general illumination applications where consistent and controllable LED brightness is crucial.
Key electrical characteristics include a 35MHz data transfer rate and a 20ns BLANK pulse width. The constant-current value for all 16 channels is set by a single external resistor, simplifying design and component count.
