Is there any dedicated amplifier out of our portfolio, matching to internal one, for simulation ?
What will happen if coupling SN back to SO?
Is internal amplifier separated or connected to any other internal functions ?

Hi Guenter,
The DRV8703-Q1 amplifier is not a general purpose amplifier and is not recommended for other uses. Your questions have been answered below.

The amplifier team should be able to help with this.
What will happen if coupling SN back to SO?
What are you trying to do?
As mentioned above, any use of this amplifier other than the intended purpose is not recommended.
Is internal amplifier separated or connected to any other internal functions ?
The amplifier is not separated. There are three functions connected.
SP is used as part of the VDS monitor for the low side FET of half bridge 1, and must be connected to the source of the low side FET.
SO is connected to the input of a comparator to activate current regulation. This function can be disabled by connecting VREF to AVDD.
An overcurrent function, Vsp(ocp) also compares the SP - SN voltage to determine if an overcurrent event has occurred.
Hi Guenter,
The slew rate and bandwidth are not specified in the datasheet, but the Settling time is.
Please refer to the ts specification in the Current Shunt Amplifier and PWM Current Control Section of the Electrical Characteristics.
