DRV8718-Q1: Half-Bridge application with current sense-shunt: can signal SHx connect with the SNx path instead of typically SPx.

Lars Rinze

Part Number: DRV8718-Q1

I would like to to connect the SHx signal with the SNx path (see second picture).

Do you see any issues on condition that the VDS overcurrent monitor threshold will NOT be set >0.4 V (maximum fPWM would be 2KHz)?

(typical application)

Hi,

Thank you for your question. I recommend to use typical application way. SH pin voltage is used VDS/VGS monitoring and may have issue situation by connecting different voltage node originally planned.
