Making outline
- Populate back-to-back power transistor charge/discharge switches with gate-drive/protection network
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"New incorporated protection function, not USB connector/distribution-disconnect; handset size/loss/current capability unknown."
