I have a circuit where I want to replace the relays with Mosfet's. It is an H-Bridge design. I have chosen a mosfet to act as a switch, the IRL3803VPbf, which works perfectly. However, I have a gate driver that I cannot get to work correctly. The IXDN430 chip has a schematic on the pdf that simply says put VCC to 18V, Gnd to Gnd, Tie Enable high, then you have your input and output. My input is a sqaure wave from the function generator for testing purposes, and my output goes straight to my mosfet switch, which is tied to a LED to test the circuit switch. Everytime the driver is hooked up it draws a large amount of current and burns up. Does anyone have any ideas or a example circuit using a simliiar gate driver and mosfet switch?
