More Information
Summary:Presented herein are techniques for power fault management that operates without power-source-side switching. A power transmitter is configured to provide power to a current loop, and a power receiver is configured to receive the power from the current loop. The power receiver is configured to, on a periodic basis, disconnect from the current loop to stop pulling power from current loop for a period of time to enable a safety check to be performed by the power transmitter. The power transmitter is configured to monitor current on the current loop, determine whether the current level on the current loop passes the safety check within a predetermined time interval since a determination that the current level was not within a safe range, and control connectivity of the power to the current loop based on whether the safety check has or has not passed within the predetermined time interval.
