Piezo driver with EBV DC2838A

Hi there, thanks for reaching out!

Before I can give you further assistance, could you clarify the following:

1.  As to whether or not you can use the EBV DC2838 - is your intent to evaluate the concept of generating 140V for the piezo load, or are you making a final design based on the LT8365* specifically?

2. In terms of current spike detection and isolation requirements - do your sensing electronics need to be completed isolated from the piezo supply, or only current sensing on a floating 140V node?

3. What current level (milliamps/amps) and switching response time (milli/micro/nano seconds) should trigger LT8365* shutdown?

Most importantly, do you have an LTSpice schematic/simulation or a block diagram of your setup and intended circuit?

*I am assuming you meant the LT8365 as that is what the DC2838A uses. We do not have a LT3565 product (unless you mean a LTC3565, but that IC does not appear to be relevant to the application here).

Many thanks!
