Part Number:DRV8323
I design a 48V inverter with DRV8320. I would like to measure the phase currents with shunt resistor. I also like to isolate the current signal so I decided to use AMC1301 isolation amplifier. Based on the datasheet the VDD1 voltage should be generated by a zener diode from the floating power supply of the gate driver:
My question is, in the case of the DRV8320 can is use the VCP terminal (output of the charge pump circuitry) to generate the voltage using Zener diode for AMC1301?
Thank you in advanced
