FOD3120S is an isolation gate driver, designed for IGBT and other power devices used in power electronics inverters. The FOD3120S gate driver provides excellent current sourcing and sinking capabilities due to its high-density 3D-MOSFET power stage technology. This driver offers superior protection features for IGBTs and other component such as ESD protection on the IC package as well as over voltage protection. It also provides high-noise immunity, which helps to reduce EMI compliance issues.

The FOD3120S can drive both N-channel and P-channel IGBTs with a single controller, providing a simple, low-cost solution for many power electronics applications. This driver can source up to 5A and sink up to 8A, providing the power needed to drive the IGBTs in a wide range of power circuits. The FOD3120S is designed for use in high-frequency applications where exceptional high-speed switching performance is required. The FOD3120S includes a programmable input stage for precise timing control, allowing short turn-off delays and current limiting, providing improved efficiency and system performance.

The FOD3120S can be used in a variety of applications, such as solar inverters, uninterruptible power supplies, welding power supplies, motor control systems, current sensing, and other high-frequency applications. This driver is particularly well suited for applications where high speed switching is required, such as those commonly found in AC drives and power converters. The FOD3120S also offers excellent EMI performance, allowing designers to meet ever-tightening emissions regulations.

At the core of the FOD3120S is the process of reversing the photodomestic current flow from the power device to the gate using a charge pump voltage, rather than a direct connection. This allows the gate to be isolated from the high voltage of the power device, thus providing superior protection for the device and improving the system efficiency. The power transistor circuit is of a high-load current rating with a lower power supply voltage rating, providing a highly efficient solution.

The FOD3120S provides a simple yet powerful gate drive solution for IGBT and other power devices. The high-speed switching capabilities of the driver, combined with its superior protection and excellent EMI performance, makes it an ideal choice for a wide range of power electronics applications. From solar inverters, to AC drives, the FOD3120S can provide an efficient and reliable solution.
