IOUT_OC_WARN_LIMIT
This command sets the value of the output current measured by the ADC that causes an output overcurrent warning
in Amperes. The READ_IOUT value will be used to determine if this limit has been exceeded.
In response to the IOUT_OC_WARN_LIMIT being exceeded, the device:
• Sets the NONE_OF_THE_ABOVE bit in the STATUS_BYTE
• Sets the IOUT bit in the STATUS_WORD
• Sets the IOUT Overcurrent Warning bit in the STATUS_IOUT command, and
• Notifies the host by asserting ALERT pin, unless masked
The IOUT_OC_FAULT_LIMIT is ignored during TON_RISE and TOFF_FALL.
This command has two data bytes and is formatted in Linear_5s_11s format

IIN_OC_WARN_LIMIT
The IIN_OC_WARN_LIMIT command sets the value of the input current measured by the ADC, in amperes, that causes
a warning indicating the input current is high. The READ_IIN value will be used to determine if this limit has been
exceeded.
In response to the IIN_OC_WARN_LIMIT being exceeded, the device:
• Sets the OTHER bit in the STATUS_BYTE
• Sets the INPUT bit in the upper byte of the STATUS_WORD
• Sets the IIN Overcurrent Warning bit[1] in the STATUS_INPUT command, and
• Notifies the host by asserting ALERT pin
This command has two data bytes and is formatted in Linear_5s_11s format.
