LM74930-Q1: 110V DC clamp surge stopper

Part Number: LM74930-Q1

I have a battery system with 72V-110V DC output. The surge voltage will be around 200 Volts and I want to clamp it to 110V dc . There are ready-made clamp  surge protector ICs, but the clamp voltages are around 60V-80V.  Maybe I can create my own active clamp surge protector with mosfets .Can you provide  a solution for this? It would be great if it also had overcurrent protection.
Another question is if we see a surge voltage at the input, we can adjust the mosfet and clamp the appropriate voltage for the output. Yes.
 So if a voltage surge occurs at the output? Will it transmit it to the input? Moreover, can we keep the output at the clamp voltage? Because the power system feeds the motors and I have an inductive load.
The body diode of the mosfet worries me.

About designing my own active clamp circuit.
If the input is in the range I want, I can completely open the mosfet (fully conducting) in bypass mode. If the input is over 110 volts, I can operate the mosfet in the triode region and limit the output voltage.
  • Hi, 

    I am unsure if LM74930-Q1 for your use case as we use this device for an active clamp <65V. It can withstand higher voltages due to stronger MOSFET at the input side, but all the pins are rated for 65V only and hence you cant really achieve a 110V clamp.
