The FET can’t get rid of that heat but will absorb it in its thermal mass instead, heating up a little. 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?

On page 4, bottom right, there’s a graph showing the maximum safe operating area SOA of the device. That’s W dissipated in a SOT device. So if you just short its output to ground, it will die. In fact, the datasheet for the MIC states: The current might be internally limited. Unimportant 1 6. Mahendra Gunawardena 1, 9 Sign up using Facebook. At t 0 any capacitor will act like a short circuit. 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.


Email Required, but never shown. If the pulse is short enough, the FET will not heat up much and therefore survive just fine.

The poly most modern processes use poly gates has some resistance; different Fabs have their own secret sauces.

Without a gate resistor the only thing limiting the current is the gate driver’s output resistance, which is supposedly low, it would not be a good driver otherwise. I would place a 0 ohm resistor there for future experimentation.

It’s not current that kills a FET, it’s overheating. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

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.


As long as that doesn’t cause it to get hotter than its maximum junction temperature, no harm will be done.

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. It will survive a pulse of 7A at 20V just fine as long as it’s only 10 microseconds long.
