Black Box Recorder

Black Box is a powerful diagnostic tool that captures all telemetry and status information when any fault occurs.

The ISL68229 and ISL68239 continuously monitor all rail and phase information along with the time duration that

the rail has been regulating, and the tool captures that data when a fault is registered. The tool reports the first

fault bit that occurred to cause the shutdown. This diagnostic data is stored in RAM, and Black Box can be

configured to additionally write to NVM for retrieval when the system loses input power as a fault occurs. The

RAM record is updated every time a fault occurs. Black Box can write to NVM up to 10 times and provides an

option to limit NVM writing to once per power cycle to avoid filling up the available NVM space inadvertently.
