Hi TS,

This is often a problem due to the incorrect hall sensor connections. Section 8.1.1 on page 20 of the datasheet outlines correct Hall Sensor connections for this device. I would recommend ensuring correct hall sensor connections (Phases lined up with Hall Sensors), as well as ensuring the correct bias voltage on the HX- pins if using Hall ICs.
