Hi,
I'm curently trying to design a bidirectionnal switch and I decided to go for a dual back-to-back LM5069 solution. I prototyped it with 2x LM5069EVAL boards but without the dv/dt control, it worked well.
The use case is to be able to control (switch ON / OFF) a power bus in which curent can flow in both directions.
Here are the main specs:
Voltage:
- 25V min
- 55V typical
- 60V max
Current:
-15A max
Capacitive load:
-1000uF max
The devices will be driven by a MCU by the UVLO pin.
I followed the step indicated in the excel file to design this schematic but would like a review of it.
In copy you will find the excel file completed with my specifications and the schematic I've done.
Thank you.
Best regards,
Victor G.
