STATUS REGISTER (STATUS)
The Status Register provides all the information about
what is going on within the TC664/TC665 devices. Fan
fault information, VIN status, RPM counter overflow
and over temperature indication are all available in the
Status Register. The Status Register is an 8-bit Read
only register with bits 1, 4, 6 and 7 unused. See
Register 6-4 below for the bit descriptions.

bit 7
bit 0
bit 7-6
Unimplemented: Read as ‘0’
bit 5
OTF: Over Temperature Fault Condition
For the TC664/TC665 device, this bit is set to the proper state immediately at startup and is
therefore treated as an unknown (X). If VIN is greater than the threshold required for 100% duty
cycle on VOUT (2.6 V typical), then the bit will be set to a ‘1’. If it is less than the threshold, the
bit will be set to ‘0’. This is determined at power-up.
1
= Over temperature condition has occurred.
0
= Normal operation, VIN is less than 2.6 V.
bit 4
Unimplemented: Read as ‘0’
bit 3
RCO: RPM Counter Overflow
1
= Fault condition. The maximum RPM reading of 12775 RPM in register RPM has been
exceeded. This bit will automatically reset to zero when the RPM reading comes back into
range.
0
= Normal operation. RPM reading is within limits (default).
bit 2
VSTAT: VIN Input Status
For the TC664/TC665 devices, the VIN pin status is checked immediately at power-up. If no
external thermistor or voltage output network is connected (VIN is open), this bit is set to a ‘1’.
If an external network is detected, this bit is set to ‘0’. If the VIN pin is open and SMBus operation
has not been selected in the Configuration Register, the VOUT duty cycle will default to 39.33%.
1
=VIN is open.
0
= Normal operation. Voltage present at VIN.
bit 1
Unimplemented: Read as ‘unknown’
bit 0
FF: Fan Fault
1
= Fault Condition. The value for fan RPM in the RPM Register has fallen below the value set
in the FAN_FAULT Threshold Register. The speed of the fan is too low and a fault condi-
tion is being indicated. The FAULT output will be pulled low at the same time. This fault bit
can be cleared using the Fan Fault Clear bit (FFCLR (bit 7<0>)) in the Configuration Reg-
ister.
0
= Normal Operation (default).
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit
-n = Value at POR
’1’ = Bit is set
’0’ = Bit is cleared
x = Bit is unknown
