Viper 16 hangs up

I put in a technical support request on this but no response.

I'm running a Viper16 in a simple non-isolated buck configuration as per the data sheet.

There is a spark ignitor on the board and sometimes when the spark occurs, the Viper16 shuts down. I can understand it might go into one of its overload conditions but it does not recover. Vdd sits at 12V, 0.25V on FB and 0V on LIM and COMP.

If I inject current into Vdd, the Viper16 starts again. Strange.

Has anyone had this sort of problem with the Viper16 or other Viper chips?
