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
