I would place a 0 ohm resistor there for future experimentation. In fact, the datasheet for the MIC states: Sign up using Email and Password. As long as that doesn’t cause it to get hotter than its maximum junction temperature, no harm will be done. If the pulse is short enough, the FET will not heat up much and therefore survive just fine. Owing to the fact that this gate driver features adaptive dead-time and thus monitors the gate of the MOSFET to determine when it has fully turned off, a gate resistor prevents proper sensing of the actual gate.
It’s not current that kills a FET, it’s overheating.
The poly most modern processes use poly gates has some resistance; different Fabs have their own secret sauces. Unimportant 1 6.
The current might be internally limited. My thinking is this should lead to current peaks that easily exceed the driver’s 1A maximum peak current and damage the chip, but the evaluation board demonstrates that this is not the case, what am I missing? MOSFETs like the ones in the MIC’s output stage can handle large current pulses for a short time by simply absorbing the heat generated by the pulse in their thermal mass.

Home Questions Tags Users Unanswered. The chip specifies the “typical” Irljl2803 output current as 1A, not an absolute maximum. At t 0 any capacitor will act like a short circuit. The Apps Engineer likely will not have access to any Fab details.

Irlml28033 Required, but never shown. This current is limited by its internal output resistance since there doesn’t seem to be a limiting circuit according to the datasheet’s diagram of the output stage. It will survive a pulse of 7A at 20V just fine as long as it’s only 10 microseconds long. The FET can’t get rid of that heat but will absorb it in its thermal mass instead, heating up a little.
