Working Principle of FAN3217TMX-F085

The FAN3217TMX-F085 is a dual-channel gate driver designed for driving high-current power MOSFETs and IGBTs. The device consists of two separate, independent gate driver channels, each with an integrated high-voltage N-channel MOSFET. Each gate driver channel has a high-side driver for high-side switching and a low-side driver for low-side switching. The high-side driver is designed to drive a high voltage/high current power switch, while the low-side driver is designed to drive a low voltage/low current power switch.In operation, the Gate Control (GC) input pins are used to control the gates of the two power switches. The high-side driver is responsible for turning on the high-side power switch, while the low-side driver is responsible for turning on the low-side power switch. When the GC pin is high, the high-side driver will turn on the high-side power switch and the low-side driver will turn off the low-side power switch. Conversely, when the GC pin is low, the low-side driver will turn on the low-side power switch and the high-side driver will turn off the high-side power switch.The FAN3217TMX-F085 can be configured so that the dead time between the two channels is adjustable. This allows for a more precise control of the power switches without affecting the system’s performance. The device also offers adjustable current limit and over-temperature protection. This provides additional fault protection for the device and system, allowing it to safely handle large currents without damaging the device or system. The FAN3217TMX-F085 is designed for use in high-power switching applications, such as motor control, power supplies, and inverters. This device is the ideal choice for driving high-current power switches thanks to its fast turn-on and turn-off times, adjustable dead time, and adjustable current limit. Additionally, the device is robust and reliable and provides protection features to ensure safe operation.
