Use this path if your program needs USB-C power negotiation and a controlled power path—such as service power, accessory power, configuration/debug ports, or system power interfaces.

Deliverables are packaged to be reviewable, version-controlled, and manufacturable.

• Program definition: 48V/240W targets, DRP policy, use cases, thermal envelope (program-defined)
• Power-path architecture: bidirectional power routing, inrush strategy, protection boundaries, safe-state transitions
• Firmware/protocol integration: negotiation state machine, role switching logic, error handling, recovery behavior
• Diagnostics & event logs: PD events, protection trips, counters, and service signals
• Validation evidence package: test plan + pass/fail summary + issue log + closure tracking
• Production handoff: EOL test items, acceptance criteria, traceability fields (program-defined)

To propose accurately for 48V / 240W bidirectional programs, we typically request:

• DRP policy: when to act as sink vs source, and role-switch triggers
• Use cases: charging, discharging/supplying, service port, accessory power, debug/config
• Thermal envelope: enclosure constraints, connector/cable assumptions, ambient profile
• Protection expectations: OVP/OCP/OTP thresholds philosophy, reverse current behavior, safe state definition
• Program phase and timeline (EVT/DVT/PVT) + volume expectations (if available)

1. Define role and constraints: sink/source/DRP, target power levels, thermal envelope, use cases
2. Establish safety boundaries: power path protection strategy and fail-safe behavior
3. Implement protocol integration: negotiation logic, state machine, error handling
4. Validate under profiles: normal operation + edge cases + recovery behavior
5. Freeze release artifacts: firmware/config package, documentation, and production handoff checklist

• Negotiation success rate across defined cables/adapters and environments (program-defined)
• Time-to-power and transition stability during role switching
• Deterministic fault handling (safe fallback + recovery) under stress profiles
• Thermal behavior at 240W (connector/cable/interface temperature rise)
• Manufacturing readiness: EOL cycle time, pass yield, log completeness (program-defined

Yes. We support sink/source/DRP with program-defined policies and deterministic state transitions, plus validation evidence for edge cases.

A. Program-defined. We deliver integration-ready architecture, firmware/protocol logic, diagnostics/logging, validation evidence, and production handoff artifacts; hardware packaging depends on your platform constraints.

A. Target power levels, role (sink/source/DRP), use cases, thermal envelope, protection expectations, and program timeline.

A. Power-path safety and thermal limits: inrush/hot-plug behavior, connector/cable heating, reverse current scenarios, and deterministic protection/recovery.

Share your power targets and constraints. We’ll respond with a structured proposal outline and next-step questions.

We deliver integration-ready documentation and validation evidence; certification execution depends on program plan and lab partner. For bidirectional 48V/240W programs, the highest risk is not negotiation—it is undefined authority during faults and derating. A responsibility matrix is required before EVT.
