UCC25600: GD max pull-down current

Hi Manikanta,

Can you clarify what the 0.4A Source is?, My understanding is that 25mA is when the transistor is normally driven, while the current to ground should be the pull current, and the two should be different.

Is my understanding correct?

Hi Manikanta,

So 0.4A source is just a momentary rush of 300ns? This is when the MOS tube is normally driven, what if GD1 or GD2 connects the resistor to GND? Should the maximum continuous current to the ground be 0.4A? My current resistance to the ground is 126 ohms, and the continuous current is 80mA。

Hi Manikanta,

Is my understanding correct? the value of the on resistance of the upper mosfet of the drive is  4~10 Ohm? and the current of GD1 or GD2 can be obtained by dividing the actual voltage of GD1 or GD2 by the resistance connected to GND, then the actual current is about 80mA, so I would like to confirm finally that when GD1 or GD2 connects the resistance to GND, in this case, Is the maximum continuous current tolerated by GD1 or GD2 0.4A?

Hi Manikanta,

I'm posting this question on behalf of a customer, I'll set up a meeting. Can you tell me your preferred time? is  27/04 12:00 PM CST okay with you?
