PRODUCTION DATA
A buck overcurrent event is sensed by monitoring the current flowing through 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 automatic retry setting. In this setting, after a buck OCP event is detected, all the buck regulator’s FETs are disabled and the nFAULT pin is driven low. The FAULT, BK_FLT, and BUCK_OCP bits are latched high in the SPI registers. Normal operation starts again automatically (driver operation and the nFAULT pin is released) after the tBK_RETRY time elapses. The FAULT, BK_FLT, and BUCK_OCP bits stay latched until the tRETRY period expires.
