IOUT_OC_FAULT_LIMIT

The IOUT_OC_FAULT_LIMIT command sets the value of the per phase output current, in amperes, which will cause the

OC supervisor to detect an output overcurrent fault. The LTC3888-1 uses IOUT_CAL_GAIN and the voltage between the

ISENSE inputs and IREF to determine output current. Output overcurrent faults are ignored during turn-on and turn-off

output transitions.

This command has two data bytes in Linear_5s_11s format.

IOUT_OC_WARN_LIMIT

The IOUT_OC_WARN_LIMIT command sets the value of the average per phase output current measured by the ADC,

in amperes, that causes an output overcurrent warning. To provide meaningful responses, this value should be set

below IOUT_OC_FAULT_LIMIT. If the IOUT_OC_WARN_LIMIT is exceeded, the device:

• Sets the IOUT Bit in the STATUS_WORD

• Sets the IOUT Overcurrent Warning Bit in the STATUS_IOUT Command

• Notifies the Host by Asserting ALERT, Unless Masked

Output overcurrent warnings are ignored during turn-on and turn-off output transitions.

This command has twºo data bytes in Linear_5s_11s format.
