PRODUCTION DATA
A buck overcurrent event is sensed by monitoring the current flowing through the buck regulator’s FETs. If the current across the buck regulator FET exceeds the IBK_OCP threshold for longer than the tBK_OCP deglitch time, an OCP event is recognized. The buck OCP mode is configured in the automatic retry setting. In this setting, after a buck OCP event is detected, all the buck regulator’s FETs are disabled and the FAULTZ pin is driven low. Normal operation starts again automatically (driver operation and the FAULTZ pin are released) after the tBK_RETRY time elapses.
