If the pulse is short enough, the FET will not heat irlm,2803 much and therefore survive just fine. 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.

On page 4, bottom right, there’s a graph showing the maximum safe operating area SOA of the device. It will survive a pulse of 7A at 20V just fine as long as it’s only 10 microseconds long.
At t 0 any capacitor will act like a short circuit. The Apps Engineer likely will not have access to any Fab details.
That’s W dissipated in a SOT device. The chip specifies the “typical” LO output current as 1A, not an absolute maximum. Sign up using Facebook. Sign up using Email and Password.
Mahendra Gunawardena 1, 9 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 FET can’t get rid of that heat but will absorb it in its thermal mass instead, heating up a little. Sign up datashdet log in Sign up using Google.
Owing to daatsheet 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.
It won’t be able to deliver 1A or more continuously, however – it can only do that for short pulses. It’s not current that kills a FET, it’s overheating.
The current might be internally limited. Unimportant 1 6. Home Questions Tags Users Unanswered. 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 irlnl2803 that this is not the case, what am I missing?
I would place a 0 ohm resistor there for future experimentation.
