PRODUCTION DATA.
The IOUT_OC_FAULT_LIMIT command sets the value of the output current, in amperes, that causes the overcurrent detector to indicate an overcurrent fault condition. The IOUT_OC_FAULT_LIMIT should be set equal to or greater than the IOUT_OC_WARN_LIMIT. Writing a value to IOUT_OC_FAULT_LIMIT less than IOUT_OC_WARN_LIMIT causes the device to set the CML bit in the STATUS_BYTE and the invalid data (ivd) bit in the STATUS_CML registers as well as assert the SMBALERT signal. The contents of this register can be stored to nonvolatile memory using the STORE_DEFAULT_ALL command. Since 2-LSBs are not stored in EEPROM, on STORE, always round up. If IOUT_OC_FAULT_LIMIT [1:0] > 0, add 1 to IOUT_OC_FAULT_LIMIT [6:2]
The IOUT_OC_FAULT_LIMIT takes a two-byte data word formatted as shown below:
