Isolators - Gate Drivers are special components designed to facilitate the processes of connecting and disconnecting two parts of a circuit. In particular, they are typically used in high current applications, where a switching component is necessary. The SI82394AD4-IS is a high-speed, high-performance isolated gate driver manufactured by Texas Instruments. It is designed for use in isolated gate drive applications on board the transformer of isolated and floating gate circuits.

The SI82394AD4-IS is a non-isolated, uni-polar driver. That is, it is powered and operated from a single voltage source, and can drive multiple gates based on input logic levels. It is comprised of two channels, each consisting of a driving portion and a controlling portion. The controlling portion acts as an interface between the logic signal and the driving portion, providing a level of isolation between the two sections. The driving section then takes the logic signal from the controller portion, and amplifies the input signal, before driving the gate.

The SI82394AD4-IS driver has the capability to deliver maximum output current of 500 mA, which makes it an ideal choice for most isolated gate drive applications. It carries an isolation rating of 15 kV with RMS test voltage for up to 2 ms operating time. This makes the driver suitable for applications featuring extreme high voltage transients. It also features a common mode transient immunity rating of up to 10 kV/μs, and a high common to differential mode noise ratio of up to 30 dB.

The SI82394AD4-IS is typically used in applications such as switch mode power supplies, motor drives, and isolated power connectors and systems. It offers Enhanced Active Miller Clamping (eAMC) technology, which allows the driver to accurately control the voltage and current levels while switching the gate. This feature helps reduce noise levels, eliminates the need for hardware level shifters, and increases the overall switching performance. Additionally, TI’s eAMC technology helps improve EMC and EMI performance.

The SI82394AD4-IS is an ideal choice for applications requiring high performance isolated gate drive. Its high speed, isolation rating, and common mode transient immunity provide reliable operation in a wide variety of applications. It is also suitable for applications where noise levels must be minimized, such as in switch mode power supplies and motor drives.
