Part Number:DRV8701
We would like to use the DRV8701. The question is:
The built-in "overcurrent monitor" protects especially the high side FET. We require at least two different cut-off limits for our application (for example 1A and 3A). Due to our system architecture, we can not guarantee that the voltage VM will always drain via the shunt resistor. It is also conceivable that the current flows from VM via the high side FET directly to the ground. How does the DRV8701 know, at which current the used highside FET is destroyed, so that it is switched off before?
Thank you for your response.
