I have a customer board in which the VLS_OUT has gone low permanently (shows less than 2V), The customer was testing a motor control application and reported application failing at current levels of around 4 Amps. The hardware is designed to sustain well above 20Amps. What can be probable cause for this scenario. Charge pump section is not populated on board and Corresponding VCP and CP pins are Not connected anywhere.
