PMIC - LED Drivers covers a wide range of applications, including lighting, display, testing and other devices. TLD1125ELXUMA1 is a LED driver IC designed for automotive and general-purpose LED lighting applications. It features a wide dimming range, active and passive control, and open-loop or closed-loop protection. This IC works with forward and reverse current sense techniques and ensures that the LED light emitted is consistent and stable. Furthermore, the IC enables dynamic balancing of forward and reverse currents, even after a short circuit condition. This allows for better control of the LED current and enhanced dimming performance.

The TLD1125ELXUMA1 integrated circuit operates at a frequency of 200 kHz and can be used in lighting circuits to drive and control current-driven LEDs. This IC boasts a high operating frequency, enabling efficient linear and pulse-width modulated (PWM) dimming performance with low EMI. With a typical forward voltage of 3.2 V, it provides sufficient forward and reverse current sourcing and sinking capabilities. Its ultra-low power consumption design allows it to be used in automotive, LED lighting, LED display, and other general-purpose applications.

The IC employs a unique control topology that offers excellent light source stability, enabling the LEDs to have consistent and uniform brightness. This approach uses both active and passive control to provide constant current outputs and eliminate undesired current fluctuation. It also prevents overshoot and under-delivery. The TLD1125ELXUMA1 comes with two operating modes, open-loop and closed-loop. The open-loop mode operates with fixed-range variable outputs and is suitable for applications that require higher stability. The closed-loop mode offers more accurate outputs, making it suitable for LED applications that require more precise outputs.

This LED driver IC supports a wide dimming range, from 0.1 to 100 % PWM, in forward and reverse control direction. It is equipped with short circuit protection and thermal protection to prevent excessive current and thermal damage. Additionally, it can be used to balance forward and reverse currents, even after a short circuit occurs. This ensures that the LED current is kept within its acceptable range and that the LEDs will not be damaged due to excessive current.

Overall, the TLD1125ELXUMA1 is an excellent LED driver IC for automotive and general-purpose LED lighting applications. Its support for wide dimming range, open-loop and closed-loop protection, and active and passive control ensures that LEDs will emit consistent and stable lighting. Its ability to balance forward and reverse current after a short circuit condition is an added benefit. With its high operating frequency, it provides efficient linear and PWM dimming performance with low EMI. Finally, its ultra-low power consumption makes it suitable for many automotive, LED lighting, and general-purpose applications.
