The FOD8316 Isolated Gate Driver is a highly integrated, single-channel, isolated gate driver designed for use as an isolated gate drive control IC for management of medium power switching operations. It incorporates a bi-directional isolation (BI-ISO) technology which reduces power losses, provides EMI and ESD suppression, and boosts system stability. The FOD8316 has both input and output isolated and includes protection features and integrated circuitry to minimize external components in most applications.

The primary application field is in the medium power switching control of industries such as automotive, renewable energy, air conditioning, and factory automation. It is ideal for accurately driving a wide range of switching devices such as power MOSFETs, IGBTs, and thyristors in these industries.

The FOD8316 Isolated Gate Driver has a very simple yet robust design. It uses a transformer-based isolation topology combining with advanced circuitry that provides a high-performance interface to an external switching circuit. It also includes MOSFET drivers, flyback output current detection, fault protection, and switch off detection circuits. The MOSFET driver features over-voltage and over-current protection as well as a capacitor discharge-circuit for fast switching of large loads.

The working principle of the FOD8316 Isolated Gate Driver is to provide an isolated interface between a control circuit and a high-power switching device. The FOD8316 takes a low-power input signal from the control circuit and amplifies it in order to drive the switching device. It also provides protection to the switching device by monitoring the load current and activating a latch-up protection mechanism when the load current exceeds the upper threshold. The FOD8316 also provides EMI and ESD suppression by incorporating a transformer-based isolation topology.

The FOD8316 Isolated Gate Driver is an ideal solution for medium power switching applications that require isolation, accurate control, and robust protection. It provides greater system stability, fewer losses, and improved power efficiency compared to traditional solutions. The FOD8316 requires fewer external components, it is simple to design in, and it supports a wide range of input signals such as TTL, 3.3v CMOS, and 5v CMOS.
