The TLC59210IN is a constant-current, low side, LED driver with an integrated 6-bit LED color scaler. By varying the LED brightness without changing the LED drive current, the LED can run cooler and longer, while also offering energy conservation. The device is a perfect solution for LCD backlighting, LED TV backlighting, automotive, and general LED lighting applications.

The TLC59210IN is a single die, 6-channel, constant-current LED driver with an integrated 6-bit LED color scaler. It includes 6 independent channels, each with its own current control, independent PWM inputs, and integrated current sensing. The on-board color scaler can independently adjust the output current from each channel, allowing more precise color control.

The device has an adjustable switching frequency in the range of 1kHz to 10kHz for the PWM input. It also has adjustable current outputs for each channel that can be set through a dedicated SPI interface. Furthermore, in addition to the SPI interface for current setting, it also features a serial input for 6-bit color scaler control.

In order to reduce power dissipation, the TLC59210IN is powered from a single voltage supply, usually in the range of 2.2V to 5.5V. The device includes thermal protection and over-voltage protection circuits, as well as open LED, short LED, and reversed power protection.

The working principle of the TLC59210IN is simple. By varying the LED color, brightness and output current, the device is able to maintain a given LED drive current as an independent adjustable input while all outputs are kept at the same level. This ensures that the same amount of energy is being delivered to the LED, thereby conserving power and reducing heat. The device also integrates over-voltage and over-current protection, ensuring the LED will be kept safe under any circumstances.

In summary, the TLC59210IN is a flexible and powerful LED driver solution for a variety of LED lighting applications. With its adjustable switching frequency, current outputs, and low-side LED driver, it offers efficient LED control and energy conservation. The integrated 6-bit LED color scaler also provides precise color control, making the device a perfect solution for LCD backlighting, LED TV backlighting, automotive, and other general LED lighting applications.
