TLC59282DBQR

The TLC59282 LED driver utilizes an array of 18 channels to enable up to 18 LED strings. By using on-chip dimming capability, products requiring up to 18 strings of LEDs can be created with single IC. There are a wide range of applications for this LED driver ranging from industrial, consumer, and automotive sectors. Its features make it suitable for numerous applications including high brightness LED lighting, LCD backlighting, high resolution displays, and decorative lighting.

The TLC59282 is built with a ground referenced H-Bridge. Each channel has an ‘on’ and ‘off’ switch, allowing easy control of light intensity. All these switches integrate high voltage MOSFETs, which ensures low power consumption and minimized crosstalk as well as reduced electromagnetic interference. The overall drive current is adjustable by a variable resistor and set at 5 to 15 mA. Furthermore, the device supports pulse-width modulation (PWM) dimming, which provides superior light control and smooth dimming.

In many applications, the LEDs need to be continuously lit up with the same color. The TLC59282 has a built-in ‘color detector’ that constantly monitors the voltage across its output lines. If the voltage reach exceeds the threshold, a small current will be injected through the cathodes to keep the LEDs lit up. The result is greater overall efficiency as the LEDs are turned on or off without drawing excessive current for operation.

The TLC59282 is also ideal for applications that require a high level of brightness control. It comes with an on-chip DC/DC converter, which provides significantly more current than what can be achieved with traditional AC/DC conversion techniques. This reduces output impedance and provides smooth dimming with a dynamic current range of up to 4A. Furthermore, the converter regulates output current regardless of input voltage fluctuations.

The TLC59282 is designed with a built-in over-temperature protection. The device continuously monitors the ambient temperature conditions and shuts off when it exceeds the preset limit. This prevents overheating and increases the safety of the system. In addition, the TLC59282 integrates a ‘no load current suppression’ function to further reduce power consumption in standby mode.

The TLC59282 is a powerful LED driver featuring an array of 18 channels to power up to 18 LED strings. With its adjustable drive current, color detector, on-chip DC/DC converter, and over-temperature protection, the TLC59282 is suitable for a wide range of applications including high brightness lighting, LCD backlighting, high resolution displays, and decorative lighting.
