4) Responds as specified in MFR_FAULT_RESPONSE.
5) Notifies the host using ALERT assertion (if enabled in MFR_MODE).
IOUT_OC_WARN_LIMIT (46h)
The IOUT_OC_WARN_LIMIT command sets the value of the current that causes an overcurrent warning. This value is
typically less than the overcurrent fault threshold in IOUT_OC_FAULT_LIMIT. The 2 data bytes are in DIRECT format.
In response to violation of the IOUT_OC_WARN_LIMIT, the device does the following:
1) Sets the NONE OF THE ABOVE bit in STATUS_BYTE.
2) Sets the NONE OF THE ABOVE, IOUT, and MFR bits in STATUS_WORD.
3) Sets the OC_WARN bit in STATUS_MFR_SPECIFIC.
4) Notifies the host using ALERT assertion (if enabled in MFR_MODE).
IOUT_OC_FAULT_LIMIT (4Ah)
The IOUT_OC_FAULT_LIMIT command sets the value of the current that causes an overcurrent fault. The factory
default value for IOUT_OC_FAULT_LIMIT is 0000h. This value disables the device from measuring current. Any nonzero
positive value written to IOUT_OC_FAULT_LIMIT causes the device to enable current measurement. The 2 data bytes
are in DIRECT format. In response to violation of the IOUT_OC_FAULT_LIMIT, the device does the following:
1) Sets the IOUT_OC bit in STATUS_BYTE.
2) Sets the IOUT, IOUT_OC, and MFR bits in STATUS_WORD.
3) Sets the OC_FAULT bit in STATUS_MFR_SPECIFIC.

IOUT_OC_FAULT_LIMIT VALUE
8000h to FFFFh
0000h
0001h to 7FFFh
DEVICE RESPONSE (ON THE ASSOCIATED PAGE)
Negative values are invalid.
Current measurement disabled.
Current measurement enabled.
4) Responds as specified in the MFR_FAULT_RESPONSE.
5) Notifies the host using ALERT assertion (if enabled in MFR_MODE).
OT_FAULT_LIMIT (4Fh)
The OT_FAULT_LIMIT command sets the temperature, in degrees Celsius, of the selected temperature sensor at which
an overtemperature fault is detected. The 2 data bytes are in DIRECT format. In response to the OT_FAULT_LIMIT being
exceeded, the device does the following:
1) Sets the TEMPERATURE bit in STATUS_BYTE.
2) Sets the TEMPERATURE and MFR bits in STATUS_WORD.
3) Sets the OT_FAULT bit in STATUS_MFR_SPECIFIC.
