Digital Power-Supply Controller/Monitor
with PMBus Interface
IOUT_SCALE (38h)
The IOUT_SCALE command is used to set the ratio of
the voltage at the current-sense pins to the sensed cur-
rent. For devices using a fixed current-sense resistor, it
is the same value as the resistance.
The unit of the IOUT_SCALE factor is m ? .
The 2 data bytes are in DIRECT format. Valid values are
from 0.5m ? to 5m ? .
The default IOUT_SCALE value is 0m ? .
VOUT_OV_FAULT_LIMIT (40h)
The VOUT_OV_FAULT_LIMIT command sets the value
of the output voltage measured across RS+ and RS-
that causes an output overvoltage fault.
The 2 data bytes are in DIRECT format. Valid values are
the same as VOUT_COMMAND.
The default VOUT_OV_FAULT_LIMIT value is 00h.
In response to the VOUT_OV_FAULT_LIMIT being
exceeded, the MAX8688:
1) Sets the VOUT_OV bit in the STATUS_BYTE.
2) Sets the VOUT_OV_FAULT bit in the
MFR_FAULT_STATUS register.
3) Responds as specified by VOUT_OV_FAULT_
RESPONSE bits in the MFR_FAULT_RESPONSE
register.
4) Notifies the host through FLT assertion.
VOUT_OV_WARN_LIMIT (42h)
The VOUT_OV_WARN_LIMIT command sets the value
of the output voltage measured across RS+ and RS-,
which causes an output-voltage high warning. This
value is typically less than the output overvoltage
threshold in VOUT_OV_FAULT_LIMIT.
The 2 data bytes are in DIRECT format. Valid values are
the same as the VOUT_COMMAND.
The default VOUT_OV_WARN_LIMIT value is 00h.
In response to the VOUT_OV_WARN_LIMIT being
exceeded, the MAX8688:
1) Sets the OTHER bit in the STATUS_BYTE.
2) Sets the VOUT_OV_WARN bit in the
MFR_FAULT_STATUS register.
3) Notifies the host through FLT assertion.
VOUT_UV_WARN_LIMIT (43h)
The VOUT_UV_WARN_LIMIT command sets the value
of the output voltage measured across RS+ and RS-,
which causes an output-voltage low warning. This value
is typically greater than the output undervoltage fault
threshold in VOUT_UV_FAULT_LIMIT.
This warning is masked until the output voltage reaches
the programmed voltage at startup and also during
turn-off when the POL is disabled.
The 2 data bytes are in DIRECT format. Valid values are
the same as VOUT_COMMAND.
The default VOUT_UV_WARN_LIMIT value is 00h.
In response to violation of the VOUT_UV_WARN_LIMIT,
the MAX8688:
1) Sets the OTHER bit in the STATUS_BYTE.
2) Sets the VOUT_UV_WARN bit in the
MFR_FAULT_STATUS register.
3) Notifies the host using FLT assertion.
VOUT_UV_FAULT_LIMIT (44h)
The VOUT_UV_FAULT_LIMIT command sets the value
of the output voltage measured across RS+ and RS-,
which causes an output undervoltage fault.
This fault is masked until the output voltage reaches the
programmed voltage at startup and also during turn-off
when the POL is disabled.
The 2 data bytes are in DIRECT format. Valid values are
the same as VOUT_COMMAND.
The default VOUT_UV_FAULT_LIMIT value is 00h.
In response to violation of the VOUT_UV_FAULT_LIMIT,
the MAX8688:
1) Sets the OTHER bit in the STATUS_BYTE.
2) Sets the VOUT_UV_FAULT bit in the
MFR_FAULT_STATUS register.
3) Responds as specified by VOUT_UV_FAULT_
RESPONSE bits in the MFR_FAULT_RESPONSE
register.
4) Notifies the host using FLT assertion.
IOUT_OC_FAULT_LIMIT (46h)
The IOUT_OC_FAULT_LIMIT command sets the value
of the output current, in amperes, measured across
ISN+ and ISN- that causes the overcurrent detector to
indicate an overcurrent fault condition.
The 2 data bytes are in DIRECT format. Valid values are
from 0 to 50/IOUT_SCALE amperes.
The default IOUT_OC_FAULT_LIMIT value is 00h.
In response to the IOUT_OC_FAULT_LIMIT being
exceeded, the MAX8688:
1) Sets the IOUT_OC bit in the STATUS_BYTE.
2) Sets the IOUT_OC_FAULT bit in the
MFR_FAULT_STATUS register.
