LM74502: Drive two circuits back-to-back mounted with a single LM74502

Paul-Ambroise Burdet

Part Number: LM74502

Dear all,

I was wondering if for the circuit below, there was a way to use a single LM74502 to drive 4 mosfets. (back to back mounted)

With Vin1 and Vin2 being different signals.

What would an updated circuit version so there would only be one LM74502?

Hi Paul,

Yes, I think I can come up with an application circuit to establish OV protection on two separate rails using only one LM74502 device. Let me discuss with my team internally to check for feasibility. I will get back to you in a few days.

Thanks and best regards

Hi Divyanshu,

Thanks for sharing this.
the Altium files will be ready in approx. 10 days, so if you could manage to come up with an answer before these 10 days that would be perfect!
