The VOUT_OV_WARN_LIMIT command sets the value of the output voltage that causes an output voltage high warning.
The monitored voltage must drop by at least 2% below the limit before the warning is allowed to clear. This warning is
masked until the output voltage is below this limit for the first time. The 2 data bytes are in DIRECT format. In response
to the VOUT_OV_WARN_LIMIT being exceeded, the device does the following:
1) Sets the NONE OF THE ABOVE bit in STATUS_BYTE.
2) Sets the NONE OF THE ABOVE and VOUT bits in STATUS_WORD.
3) Sets the VOUT_OV_WARN bit in STATUS_VOUT.
4) Responds as specified in the MFR_FAULT_RESPONSE.
The VOUT_UV_WARN_LIMIT command sets the value of the output voltage that causes an output undervoltage warn-
ing. The monitored voltage must increase by at least 2% above the limit before the warning is allowed to clear. This
warning is masked until the output voltage exceeds this limit for the first time. The 2 data bytes are in DIRECT format.
In response to the VOUT_UV_WARN_LIMIT being exceeded, the device does the following:
1) Sets the NONE OF THE ABOVE bit in STATUS_BYTE.
2) Sets the NONE OF THE ABOVE and VOUT bits in STATUS_WORD.
3) Sets the VOUT_UV_WARN bit in STATUS_VOUT.
4) Responds as specified in the MFR_FAULT_RESPONSE.
The VOUT_UV_FAULT_LIMIT command sets the value of the output voltage that causes an output undervoltage fault.
The monitored voltage must increase by at least 2% above the limit before the fault is allowed to clear. This fault is
masked until the output voltage exceeds this limit for the first time. The 2 data bytes are in DIRECT format. In response
to violation of the VOUT_UV_FAULT_LIMIT, the device does the following:
1) Sets the NONE OF THE ABOVE bit in STATUS_BYTE.
2) Sets the NONE OF THE ABOVE and VOUT bits in STATUS_WORD.
3) Sets the VOUT_UV_FAULT bit in STATUS_VOUT.
4) Responds as specified in the MFR_FAULT_RESPONSE.
The IOUT_OC_WARN_LIMIT command sets the value of the current that causes an overcurrent warning. The monitored
current must drop by at least 5% below the limit before the warning is allowed to clear. This warning is masked until
the current is below this limit for the first time. 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 and MFR bits in STATUS_WORD.
3) Sets the OC_WARN bit in STATUS_MFR_SPECIFIC.
4) Responds as specified in the MFR_FAULT_RESPONSE.
