Then you know how much coupled interference current the power supply can withstand.įigure 5: An effective improvement is achieved with a resistance from gate to source. Simply feed some current directly into the gate via a resistor during operation and measure the gate voltage when it reaches the critical threshold voltage.

Therefore it is immensely important that the driver keeps the gate really low impedance!īecause some datasheets today are 'glossed over' for market strategic reasons or important properties are unclearly presented, one could also test the immunity oneself.

This can cause the switching transistor to switch on undesirably and cause a bang. Interferences occurring in the device or field can, for example, bring additional charge to the gate via the parasitic mill capacity (from drain to source). Does the MOSFET gate driver have any influence in the case of disturbances? Many power supply manufacturers have to tickle out the last cent and of course, decide - for the cheaper version! After all, nothing broke during the endurance test. It is your decision whether these additional costs justify a higher reliability. I don't need to mention that this type is much more expensive.

Driver B would be much better suited, since 'low' means max.
