MCT8329A: Regarding an undervoltage failure on the GVDD pin

In a prototype motor controller using the MCT8329A, the GVDD pin failed in short-circuit mode. The output voltage is supposed to be about 13V, but no voltage is output. Also, the ceramic capacitor connected to GVDD is about 20uF, but this did not fail.

Could you please tell me what could cause the GVDD pin to fail in short-circuit mode? Also, please let me know if there is any way to prevent this.
