The UCC27200DDA is a state-of-the-art high-voltage gate driver, which combines high speed, robustness, protection and a fully-protected configuration. It is designed to drive large external N-channel MOSFETs with up to 500V supply voltages and peak currents of up to 5A. Its Gate Drivers, specifically optimized for frequency applications, make the UCC27200DDA the perfect tool for controlling high-power applications such as power supplies, motor drives and motor speed controllers. This article will discuss the application field and working principle of the UCC27200DDA.

The UCC27200DDA is typically used in applications that require high-frequency switching, such as high power supplies or motor drives. It is often used to drive N-Channel MOSFETs with high peak currents and high supply voltages, as well as providing robustness, protection and a fully protected configuration. The device features a supply voltage up to 500V, peak current of up to 5A and low quiescent current of only 1μA. It also features a fast rise and fall times of 217ns and 217ns, respectively. Additionally, its high-frequency performance is capable of up to 350KHz clock rate.

The UCC27200DDA’s Gate Drivers work using principle of gate-driven turn-off (GTO) control. This control is commonly used for power supplies and in motor engines for efficient and effective operation. The GTO control technique works by applying a negative voltage signal to the gate of the MOSFET during turn-off. This signal causes the MOSFET to catch the drift current, which in turn leads to a faster turn-off than a normal top turn-off technique. The UCC27200DDA Gate Drivers are able to utilize the GTO control easily and efficiently, while providing a protected configuration that is resistant to voltage glitches.

The UCC27200DDA also features protection and fault protection features that make it suitable for use in applications that require high-current operation. It features thermal shutdown, feedback pin-to-pin protection, low-side open drain output, and current limiter. The thermal shutdown feature allows for protection against excessive power dissipation, protecting the IC from overheating. The feedback pin-to-pin protection prevents excessive current from flowing from the input to the output, while the low-side open drain output prevents the IC from being connected to a load in reverse. The current limiter helps to limit the peak current that can flow through the IC, protecting the IC from overloads.

The UCC27200DDA is an ideal device for high-power applications that require robustness, protection and a fully-protected configuration. Its Gate Drivers are specifically optimized for frequency applications, while its protection and fault protection features ensure that the device is protected in the event of an overload or short circuit. Additionally, its fast rise and fall times make it suitable for high-frequency switching and its low quiescent current makes it a very power-efficient choice. All of these features make the UCC27200DDA a perfect solution for powering high voltage, high frequency and high-power applications.
