MOSFET Gate Driver Isolation: Why It’s Essential and How to Fix It
The Problem : When using a MOSFET to control high-power loads like motors or LEDs, the gate needs to be driven correctly to ensure fast switching and prevent damage. However, without gate driver isolation, voltage spikes or noise from the load can feed back into the control circuit, potentially damaging the microcontroller or Arduino. …
