Compute and sensing power
Camera, sensing and compute loads can have different noise, startup and power-state requirements. Build the power architecture around those dependencies and the permitted system response to a rail fault.
- Coordinate camera and processor startup
- Keep sensitive analog paths away from switching current loops
- Define supervision and recovery for critical loads
Design priorities
Translate system requirements into a rail inventory, state diagram and fault-response plan. Identify dependencies between loads so that power transitions do not create unintended operating states.
- Rail requirements and load profiles
- Supply states, sequencing and reset relationships
- Fault detection, containment and recovery
Engineering review inputs
Bring supply limits, load requirements and environmental constraints to the design discussion. Any compliance or validation target must be tied to a defined test method and an approved system requirement.
- System block diagram and interface requirements
- Operating environment and thermal constraints
- Validation scope and acceptance criteria
