Sign up using Facebook. At t 0 any capacitor will act like a short circuit. 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.
The FET can’t get rid of that heat but will absorb it in its thermal mass instead, heating up a little. Unimportant 1 6.

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. That’s W dissipated in a SOT device. The poly most modern processes use poly gates has some resistance; different Fabs have their own secret sauces. 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 resistor prevents proper sensing of the actual gate.
Email Required, but never shown. Mahendra Gunawardena 1, 9 I would place a 0 ohm resistor there for future experimentation. Post as a guest Name. 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.

The chip specifies the “typical” LO output current as 1A, not an absolute maximum. On page 4, bottom right, there’s a graph showing the maximum safe operating area SOA of the device. 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? The Apps Engineer likely will not have access to any Fab details. The current irlmp2803 be internally limited.
So if you just short its output to ground, it will die. As long as that doesn’t cause it to get hotter than its maximum junction temperature, no harm will be done.
