REQ-PT-001 — Power integrity & protection

The production test shall perform automated power verification of every B12-N_PB unit, including: 12 V input presence and polarity; controlled enable/disable of each channel regulator; verification of the V3P3_CONx and VCCO_CONx rails; detection of PGOOD and RMTPWRDn behaviour; and confirmation that over-current protection / current-limiting mechanisms respond correctly. Power testing shall validate behaviour across all five channels independently.

All power rails meet specified limits; PGOOD/RMTPWRDn behave correctly; over-current protection and current limiting respond correctly with no unexpected over-current, latch-up, or fault conditions; all five channels verified independently. (SOW §4.1, §6)
