PCS2_a158 — Dcdc Hv Mosfet Temp Too High
Full alert identifier: PCS2_a158_DcdcHvMosfetTempTooHigh
Alert description
The temperature of the thermal model for the DCDC high voltage (HV) metal-oxide-semiconductor field-effect transistors (MOSFETs) becomes too high
Potential impact
The maximum DCDC power capability may be reduced
Set condition
The temperature of the thermal model for the DCDC HV MOSFETs rises above its set limit
Clear condition
The temperature of the thermal model for the DCDC HV MOSFETs falls below its clear limit
