Hello Community,

I want to use the STHV748 for pulsing film-Arrays. The circuit is build like the reference circuit in the Application Note AN3961 figure 33.  The input line are low  so that the output from the STHV748 should bee zero. But the current consume is on the 3,3V Supply 360mA. That's definitely to much.

Has anyone an idea what the reason could bee? Below you can see my circuit around the STHV748.

Best Regards
