Can anyone please send a minimum set of config parameters and digital input settings for L9945 to - switch a high-side FET on channel 1 on and off via SPI - turn a motor in one direction on bridge 1.

No matter what we try, nothing happens. For case 2, the L9945 receives the PWM.

Thank you in advance. Best regads: Balázs Bámer

We have found the problem. The default overcurrent detection voltage was the lowest possible, to ensure the power-on behavior won't do any harm to the circuit. The L9945 kept on shutting down any FET starting to conduct immediately. By setting the OC detect voltage to a correct value the FETs could remain switched on.
