It won’t be able to deliver 1A or more continuously, however – it can only do that for short pulses. I would place a 0 ohm resistor there for future experimentation.

The chip specifies the “typical” LO output current as 1A, not an absolute maximum. It’s not current that kills a FET, it’s overheating. If the pulse is short enough, the FET will not heat up much and therefore survive just fine.

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

At t 0 any capacitor will act datashet a short circuit. Post as a guest Name. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

The FET can’t get rid of that heat but will absorb it in its datadheet mass instead, heating up a little. Mahendra Gunawardena 1, 9 Email Required, but never shown. 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. So if you just short its output to ground, it will die. The current might be internally limited.

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.

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 lrlml2803.

On page 4, bottom right, there’s a graph showing the maximum safe operating area SOA of the datasgeet. 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 datasheft, a gate resistor prevents proper sensing of the actual gate.

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.
