VALUE
OT_FAULT_ RESPONSE 0x50 Action to be taken by the device when an external
overtemperature fault is detected,

UT_FAULT_ RESPONSE 0x54 Action to be taken by the device when an external
undertemperature fault is detected.
R/W Byte Y Reg Y 0xB8
OT_FAULT_RESPONSE
The OT_FAULT_RESPONSE command instructs the device on what action to take in response to an external overtem-
perature fault on the external temp sensors. The data byte is in the format given in Table 9.
The device also:
• Sets the TEMPERA
TURE bit in the ST
ATUS_BYTE
• Sets the Overtemperature Fault bit in the STATUS_TEMPERATURE command, and
• Notifies the host by asserting ALERT pin
This condition is detected by the ADC so the response time may be up to 100ms.
This command has one data byte.
UT_FAULT_RESPONSE
The UT_FAULT_RESPONSE command instructs the device on what action to take in response to an external undertem
-
perature fault on the external temp sensors. The data byte is in the format given in Table 9.
The device also:
• Sets the TEMPERATURE bit in the ST
ATUS_BYTE
• Sets the Undertemperature Fault bit in the STATUS_TEMPERATURE command, and
• Notifies the host by asserting ALERT pin
This condition is detected by the ADC so the response time may be up to 100ms.
This command has one data byte.
