Isolators - Gate Drivers provide an integrated solution for isolated signal transmission between the controller and the gate driver. The FOD8314T is a non-isolated gate driver specifically designed for driving high-side and low-side N-channel MOSFETs or IGBTs. It utilizes advanced gate driver technology for high-speed pulse width modulation (PWM) and enhance power density control.

The FOD8314T is an ideal gate driver for applications in telecommunication, automotive, industrial, and consumer electronics, especially in areas where high voltage or high frequency driving is required. It features increased isolation of control and power signals, which ensures stability and accuracy in operation. It also supports both high voltage and low voltage operation, allowing for flexibility in the design of equipment.

The FOD8314T operates from an input voltage range of 2.5V to 5V and provides an output current up to 6A. It includes two high voltage outputs, each with a high current (6A max), and two low voltage outputs, each with a low current (2.5A max). The output signals are not inverted, and the device switches at the supply voltage, making it suitable for both low and high voltage applications. It also features a maximum data rate of 900kbps.

The FOD8314T uses an optocoupler-based design that provides electrical isolation and prevents the coupling of switching noise between the gate driver and the controlled output section. The optocoupler is integrated with a latching circuit, which allows the gate driver to latch the voltage in a particular section, eliminating the need for external control circuitry. This allows for faster switching speeds and improved power efficiency.

The FOD8314T also features a proprietary circuit architecture that provides improved power efficiency and enhanced reliability. It utilizes a dual-channel low-side drive, which allows it to be used in applications such as half-bridge controllers, multiple inverter controllers, and other power conversion systems.

Overall, the FOD8314T provides a high performance gate driver with integrated signal isolation, low power consumption and high resolution control. Its advanced design makes it ideal for applications in telecommunication, automotive, industrial, and consumer electronics. The FOD8314T is an excellent choice for applications that require high voltage and high frequency driving.
