I would place a 0 ohm resistor there for future experimentation. My thinking is this datasheft 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.

At t 0 any capacitor will act like a short circuit. On page 4, bottom right, there’s a graph showing the maximum safe operating area SOA of the device. The FET can’t get rid of that heat but will absorb it in its thermal mass instead, heating up a little. Home Questions Tags Users Unanswered. The Apps Engineer likely will not have access xatasheet any Fab details. Without a gate resistor the only thing limiting the current is the gate driver’s output resistance, which is irrlml2803 low, it would not be a good driver otherwise.

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

Post as a guest Name. In fact, the datasheet for the MIC states: So if you just short its output to ground, it will die.

The current might be internally limited. Datasgeet up or log in Sign up using Google. Mahendra Gunawardena 1, 9 That’s W dissipated in a SOT device.

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.

Unimportant 1 6. The chip specifies datasheef “typical” LO output current as 1A, not an absolute maximum. It will survive a pulse of 7A at 20V just fine as long as it’s only 10 microseconds long. 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 ilrml2803 prevents proper sensing of the actual gate.

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.

It’s not current that kills a FET, it’s overheating. Email Required, but never shown.
