Pin "F"

F pin is an input used to import a feedback of the field driver activity. The signal coming from

field is compared to a threshold VFdet and forwarded to a µC timer port.

The F signal behavior is related to the system configuration (low side or high side).

4.3.12

Pin "CSA_IN"

The CSA_IN pin is an input dedicated to rotor current sensing in high side configuration

only.

The rotor current can be measured by means of an external sense resistor.

The current sense amplifier output is connected to the µC AIN0 analog input.

Rsense must be inserted between MOS drain and A+/B+, keeping all connections towards

CSA_IN A+/B+ EPONA pins as short as possible.
