That’s W dissipated in a SOT device.

On page 4, bottom right, there’s a graph showing the maximum safe operating area SOA of the device. Sign up using Email and Password. The Apps Engineer likely will not have access to any Fab details. Without a gate resistor the only thing limiting the current is the gate driver’s output resistance, which irlkl2803 supposedly low, it would not be a good driver otherwise. Sign up using Facebook.

IRLML2803 Datasheet

So if you just short its output to ground, it will die. The FET can’t get rid of that heat but will absorb it in its thermal mass instead, heating up a little. It won’t be able to deliver 1A or more continuously, however – ielml2803 can only do that for short pulses. At t 0 any capacitor will act like a short circuit. 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.

This current is datasyeet 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. The poly most modern processes use poly gates has some resistance; different Fabs have their own secret sauces. Post as a guest Name.

It will survive a pulse of 7A at 20V just fine as long as it’s only 10 microseconds long. Email Required, but never shown.

Home Questions Tags Users Unanswered. I would place a 0 ohm resistor there for future experimentation. 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?

If the pulse is short enough, the FET will not heat up 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. It’s not current that kills a FET, it’s overheating. As long as that doesn’t cause it to get hotter than its maximum junction temperature, no harm will be done.

The current might be internally limited. In fact, the datasheet for the MIC states: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
