LED drivers are an important component of LED-based lighting, as they are used to accurately control the current supply to LEDs, thereby ensuring an even brightness and efficient operation of the light source.Typically, LED drivers are integrated circuits with built-in current and voltage regulation capability, which helps to reduce component-level design complexity, and makes LED driver applications flexible and less costly.The TLC59711PWPR is a triple-channel LED Driver with over-voltage protection from Texas Instruments. It features a wide operating voltage range from 10 V to 38 V and a wide temperature range from -40 °C to +85 °C. The integrated dimming engine supports a variety of dimming mode algorithm, including leading-edge andtiming dimming. In addition, an internal power-on reset circuitry prevents any current overflowing.The TLC59711PWPR is designed for use in automotive headlight, daytime running light and rear light applications.

The TLC59711PWPR integrates three integrated switching PMOS (p-channel MOSFETs) to each channel, and with two input pins to control the brightness of each LED. The two input pins are EN1 and EN2, along with the associated logic low and logic high input states. The two input pins allow the user to program the motor current, create predefined light curves, as well as program multiple on/off/dimming transitions. Additionally, the TLC59711PWPR can be configured in a PWM (pulse width modulation) mode to reduce current ripple.The TLC59711PWPR features an advanced safety protection system that prevents any current surge from damaging the LEDs by monitoring the output current and limiting the current during over-current conditions. The active protection system also allows for an adjustable delay time before the voltage regulation takes place.

The TLC59711PWPR is also capable of operating in a constant current mode, allowing the user to set a desired current value and maintain it regardless of input voltage fluctuations. In order to ensure maximum efficiency and system reliability, the IC can be configured to work with different types of LEDs, including standard, high power and mid power LEDs, as well as multi-die packages.The TLC59711PWPR is available in an 8-pin DSBGA (dual signal ball grid array) package, which reduces size and simplifies the design-in process. This makes it ideal for automotive and other space-constrained applications.

In summary, the TLC59711PWPR is a triple-channel LED Driver with over-voltage protection from Texas Instruments and is ideally suited for automotive headlight, day time running light and rear light applications. It offers a wide operating voltage range and temperature range, built-in current and voltage regulation capability, active safety protection circuitry and adjustable delay before the voltage regulation takes place, internal power-on reset circuitry, user programmable light curves, two input pins to control the brightness of each LED and much more. This makes the TLC59711PWPR a great choice for designers looking for a reliable and efficient LED driver solution.
