I have a question for all who read this. Please help me, Why gate drive circuits have two method(or more?) high and low - side . And each method they are what differrent and how to use ?
In my project choose IRF250N power mosfet for switch but driver ic I not sure between TC4428 or TLP250 . Help me for selected and method to driver(high or low) . When system is 50 VDC , 500 W
It all depends upon whether the load needs to be grounded. If so, then you need a high-side driver. If not then you can use either a high-side or low-side driver.
A low-side driver has the advantage that you can use a single grounded transistor which is relatively easy to directly drive. A high-side driver requires a floating transistor which generally requires additional circuitry to drive.

Sorry i give wrong mosfet. Change to IRFP250N is corrected.
