On page 4, bottom right, there’s a graph showing the maximum safe operating area SOA of the device. 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. Mahendra Gunawardena 1, 9 Sign up using Facebook. My thinking is this should lead to current peaks that easily exceed the driver’s 1A maximum peak current and damage irlml28003 chip, but the evaluation board demonstrates that this is not the case, what am I missing?

I would place a 0 ohm resistor there for future experimentation. In fact, the datasheet for the MIC states: Post as a guest Name. The FET can’t get rid of that heat but will absorb it in its thermal mass instead, heating up a little. 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.

Email Required, but never shown. The poly most modern processes use poly gates has some resistance; different Fabs have their own secret sauces. The chip specifies the “typical” LO output current as 1A, not an absolute maximum. That’s W dissipated in a SOT device.

So if you just short its output to ground, it will die. 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 datahseet turned off, a gate resistor prevents proper sensing of the actual gate.

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’s not current that kills a FET, it’s overheating.

By using our site, you acknowledge that you have read and understand satasheet Cookie PolicyPrivacy Policyand our Terms of Service. The current might be internally limited. It will survive a pulse of 7A at 20V just fine as long as it’s only 10 microseconds long. 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.
