FDA217S are gate drivers with high isolation voltage and wide temperature range. They are used to drive power IGBTs or MOSFETs in various applications such as motor control, power supply, electric vehicle, and renewable energy systems. It is one of the most popular isolated gate drivers in industry.The FDA217S is an isolation IGBT/MOSFET gate driver with floating power supply that operates with an input voltage from 4 V to 18 V and an output voltage from 4 V to 18 V. The maximum isolation voltage of the device is 4 kV and the isolation resistance is at least 1 GΩ. The FDA217S has a temperature range of -40 to +125℃ and offers a wide range of features including a built-in over-voltage protection, reverse-battery protection, over-current protection, and frequency limit function.The working principle of FDA217S is based on the transformer-coupled gate drive principle. The device consists of a signal transformer and two controllable power switches S1 and S2. The power switch is used to drive the IGBT/MOSFET gate. The reason why the FDA217S can achieve high isolation voltage is due to the signal transformer that isolates the gate drive signals from the power switch.The operating conditions of the FDA217S are determined by the input and output voltage. The device can be used in applications with different rates of gate charging current. The rate of gate charging current is limited by the device’s own slew rate. The slew rate can be adjusted by changing the signal frequency.The FDA217S has become popular in a variety of applications due to its high-isolation voltage, wide temperature range, and built-in protection features. It is used in motor control in terms of managing the speed and torque of the motors, electric vehicles, solar power systems, wind power systems, and power supply circuits. The FDA217S is a versatile device that can be used in a variety of high-voltage systems where failure due to voltage spikes is not acceptable. Its superior insulation performance makes it one of the most reliable gate drivers in industry.
