CGD1700HB2M-UNA Test

epool

Hello,

I am currently trying to test the CGD1700HB2M-UNA board without MOSFETs connected at the output, that is, the Gate-Source connections of High and Low devices of the board are floating (connectors JB2 and JB3). Because of the floating output, it seems that the board sends a fault "state" that disables the output signals.

Is there any way to operate the board while the outputs are floating?

Another feature I am not sure if I am setting correctly is the RESET/EN functionality located in Pin 15 from connector JT1 (JT1 is located at the CGD1700HB2M-UNA board). According to TI UCC21710 datasheet (attached), that PIN is needed to enable the output of the gate driver. I have set this connection to 5V. Is this correct? Or maybe this is also generating a fault condition? What should be the correct setting for this connection?

Thanks
