PRODUCTION DATA
The device supports eight different decay modes, as shown in Table 7-7. The current through the motor windings is regulated using an adjustable fixed-time-off scheme which means that after any drive phase, when a motor winding current has hit the current chopping threshold (ITRIP), the device places the winding in one of the eight decay modes for tOFF. After tOFF, a new drive phase starts.
