their default power up states. The Configuration Regis-
ter and the FAN_FAULT Register maintain the states
they were in prior to the device being put into the shut-
down mode. Since these are the registers which control
the parts operation, the part does not have to be repro-
grammed for operation when it comes out of shutdown
mode.

SMBus Interface (SCLK & SDA)
The TC664/TC665 feature an industry standard, 2-wire
serial interface with factory-set addresses. By commu-
nicating with the TC664/TC665 device's registers,
functions like PWM duty cycle, low power shutdown
mode and fan RPM threshold can be controlled. Critical
information, such as fan fault, over temperature and fan
RPM, can also be obtained via the device data regis-
ters. The available data and control registers make the
TC664/TC665 devices very flexible and easy to use. All
of the available registers are detailed in Section 6.0.
4.11
SMBus Slave Address
The slave address of the TC664/TC665 devices is
0011 011
. This is a fixed address. This address is dif-
ferent from industry-standard digital temperature sen-
sors (like the TCN75) and, therefore, allows the TC664/
TC665 to be utilized in systems in conjunction with
these
components.
