PRODUCTION DATA
An analog current-limit circuit on each FET limits the current through the FET by removing the gate drive. If this analog current limit persists for longer than tDEG, all FETs in the H-bridge are disabled. Operation resumes automatically after tRETRY has elapsed. Overcurrent conditions are detected on both the high-side and low-side FETs. A short to the VM pin, GND, or from the OUT1 pin to the OUT2 pin results in an overcurrent condition.
