Description STTS75
1 Description
The STTS75 is a high-precision CMOS (digital) temperature sensor IC with a delta-sigma
analog-to-digital (ADC) converter and an I
for general applications such as personal computers, system thermal management,
electronics equipment, and industrial controllers, and is packaged in the industry standard
8-lead MSOP(TSSOP) and SO8 packages.
The device contains a band gap temperature sensor and programmable 9- to 12-bit ADC
which monitor and digitize the temperature to a resolution up to 0.0625 °C. The STTS75 is
typically accurate to (±3 °C - max) over the full temperature measurement range of
–55 °C to 125 °C with ±2 °C accuracy in the –25 °C to +100 °C range. At power-up, the
STTS75 defaults to 9-bit resolution for software compatibility with the STLM75.
The STTS75 is specified for operating at supply voltages from 2.7 V to 5.5 V. Operating at
3.3 V, the supply current is typically (75 µA).
The onboard delta-sigma analog-to-digital converter (ADC) converts the measured
temperature to a digital value that is calibrated in °C; for Fahrenheit applications a lookup
table or conversion routine is required.
The STTS75 is factory-calibrated and requires no external components to measure
temperature.
1.1 Serial communications
The STTS75 has a simple 2-wire I2C-compatible digital serial interface which allows the
user to access the data in the temperature register at any time. It communicates via the
serial interface with a master controller which operates at speeds up to 400 kHz. Three pins
(A0, A1, and A2) are available for address selection, and enable the user to connect up to 8
devices on the same bus without address conflict.

C-compatible serial digital interface. It is targeted
In addition, the serial interface gives the user easy access to all STTS75 registers to
customize operation of the device.
1.2 Temperature sensor output
The STTS75 temperature sensor has a dedicated open drain overlimit signal/alert
(OS
/INT/Alert) output which features a thermal alarm function. This function provides a
user-programmable trip and turn-off temperature. It can operate in either of two selectable
modes:
● Section 2.3: Comparator mode, and
● Section 2.4: Interrupt mode.
At power-up the STTS75 comes up in 9-bit mode and immediately begins measuring the
temperature and converting the temperature to a digital value. The resolution of the digital
output data is user-configurable to 9, 10, 11, or 12 bits which correspond to temperature
increments of 0.5 °C, 0.25 °C, 0.125 °C, and 0.0625 °C, respectively.

Operation STTS75
2 Operation
After each temperature measurement and analog-to-digital conversion, the STTS75 stores
the temperature as a 16-bit two’s complement number in the 2-byte temperature register.
The most significant bit (S, bit 15) indicates if the temperature is positive or negative:
● for positive numbers S = 0, and
● for negative numbers S = 1.
The most recently converted digital measurement can be read from the temperature register
at any time. Since temperature conversions are performed in the background, reading the
temperature register does not affect the operation in progress.
Bits 3 through 0 of the temperature register are hardwired to logic '0.' When the STTS75 is
configured for 12-bit resolution, the 12 MSBs (bits 15 through 4) of the temperature register
will contain temperature data. For 11-bit resolution, the 11 MSBs (bits 15 through 5) of the
temperature register will contain data, and bit 4 will read out as logic '0.' For 10-bit
resolution, the 10 MSBs (bits 15 through 6) will contain data, and for 9-bit resolution the
9 MSBs (bits 15 through 7) will contain data and all unused LSBs will contain '0s.'
Table 4 on page 15 gives examples of 12-bit resolution digital output data and the
corresponding temperatures. The data is compared to the values in the T
registers, and then the OS
operating mode. The number of T
/INT is updated based on the result of the comparison and the
OS
and T
bits used during the thermostat comparison

is equal to the conversion resolution set by the FT1 and FT0 bits in the configuration
register. For example, if the resolution is 9 bits, only the 9 MSBs of T

used by the thermostat comparator. The alarm fault tolerance is controlled by the FTI and
FTO bits in the configuration register. They are used to set up a fault queue. This prevents
false tripping of the OS
/INT pin when the STTS75 is used in a noisy environment (see
Table 2 on page 14).

The STTS75 also supports a special one-shot mode feature that performs a single
temperature measurement and returns to shutdown mode. This is especially useful for lowpower applications. This features is accessed by first putting the device in shutdown mode,
then enabling the one-shot mode (OSM) bit in the configuration register.
The active state of the OS
/INT output can be changed via the polarity (POL) bit in the
configuration register. The power-up default is active-low.
If the user does not wish to use the thermostat capabilities of the STTS75, the OS
output should be left floating.

Operation STTS75
2.2 Thermal alarm function
The STTS75 thermal alarm function provides user-programmable thermostat capability and
allows the STTS75 to function as a standalone thermostat without using the serial interface.
The OS
/INT output is the alarm output. This signal is an open drain output, and at power-up,
this pin is configured with active-low polarity by default.
2.3 Comparator mode
In comparator mode, each time a temperature-to-digital (T-to-D) temperature conversion
occurs, the new digital temperature is compared to the value stored in the T
registers. If a fault tolerance number of consecutive temperature measurements are greater
than the value stored in the T
register, the OS/INT output will be activated.
OS
For example, if the FT1 and FT0 bits are equal to “10” (fault tolerance = 4), four consecutive
temperature measurements must exceed T
OS
/INT output is active, it will remain active until the first time the measured temperature
drops below the temperature stored in the T

In Interrupt mode, the OS/INT output first becomes active when the measured temperature
exceeds the T
