MOSFETs like the ones datasheef 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.
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. Sign up using Facebook.

As long as that doesn’t cause it to get hotter than its maximum junction temperature, no harm will be done. Post as a guest Name. The Datasneet can’t get rid of that heat but will absorb it in its thermal mass instead, heating up a little. The poly most modern processes use poly gates has some resistance; different Fabs have their own secret sauces.
My thinking is datasheey 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? At t 0 any capacitor will act like a short circuit.
Home Questions Tags Users Unanswered. Email Required, but never shown. It won’t be able to deliver 1A or more continuously, however – it can only do that for short pulses. The Apps Engineer likely will not have access to any Fab details. Unimportant 1 6. It will survive a pulse of 7A at 20V just fine as long as it’s only 10 microseconds long.
On page 4, bottom right, there’s a graph showing the maximum safe operating area SOA of the device. Sign up using Email and Password. I would place a 0 ohm resistor there for future experimentation.
The chip specifies the “typical” LO output current as datashheet, not an absolute maximum. Mahendra Gunawardena 1, 9 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.
If the pulse is short enough, the FET will not irlkl2803 up much and therefore survive just fine. Sign up or log in Sign up using Google. It’s not current that kills a FET, it’s overheating.
