FOD3180V is an isolated gate driver from Fairchild. It can be used to drive high and low side power MOSFET and GaN FETs. It is designed for synchronous buck topology for fast switching and wide input voltage range with soft start and over current protection feature.

FOD3180V is an isolator gate driver that works by isolating two circuits from each other electrically. The isolation prevents any direct electrical connection between the two circuits, while still allowing signals to be exchanged between them. The device uses two isolated channels to provide gate drive signals to the power devices. It also isolates the power from noise and other electrical transients. The isolation eliminates the need for separate gate drivers and circuit protection components.

The FOD3180V is designed to operate from a wide range input voltage range of 4.5V-20V. It features fast rise and fall times of 16mV/nS and 25nS respectively. It can handle up to 6A peak sink current and 1.8A peak source current per channel, with peak power up to 3W. The device also features a built-in soft-start feature to reduce input surge current, as well as a built-in over-current protection to prevent accidental over current conditions.

The FOD3180V is suitable for many applications such as synchronous buck regulators, half-bridge drivers, high-side and low-side drivers, and routing with signal isolation. It is ideal for automotive, industrial and consumer applications where fast switching and high efficiency is required. The gate driver also has an operating range of -40 to 125℃, humidity range of 0 to 95%, and an isolation voltage of 1500 V RMS.

The FOD3180V isolator gate driver is a high performance, low-cost solution for driving high and low side power MOSFET and GaN FETs. It has a wide input voltage range and fast switching times, with built-in features like soft start and over-current protection. It is suitable for a variety of applications such as synchronous buck topology, half-bridge drivers, and signal routing with signal isolation. The device is designed for operation in extreme temperature and humid conditions, and it can handle peak power up to 3W.
