Dear all,


I have a SPC5777 in a mining application. The ECU ist a safety design according to SIL. Along with the MCU comes a SBC MC33908NAE wich has certain buck controllers and LDOs, a watch dog and voltage moniotor. The build in buck controllers can not be used, the MCU will be powered by a different solution. But to easy the safety certification we want to use WD and voltage monitor of MC33908NA. Is it possible to deactivate the buck controller?


Thank you for your help,

best regards,
