DRV8703-Q1: fault at -40degC

Part Number:DRV8703-Q1

Dear all,

one of my AA is using the DRV8703-Q1 to drive a motor. Everything works fine at room and hot temperature, but at -40degC the DRV8703-Q1 goes in VDS fault condition.

It could be related to the MOSFET, but even removing the VDS monitor feature the device acts as it is enabled and stops working.

Is this expected ?

Have you never seen similar behavior? 

Any suggestion ?

regards,

Domenico
