7 Detailed Description
7.1 Overview
The TMP100-Q1 and TMP101-Q1 devices are digital temperature sensors optimal for thermal management
and thermal protection applications. The TMP100-Q1 and TMP101-Q1 devices are Two-Wire, SMBus, and
I2C interface-compatible. These devices are specified over a operating temperature range of −55°C to 125°C.
The Functional Block Diagram section shows the internal block diagrams of the TMP100-Q1 and TMP101-Q1
devices.
The temperature sensor in the TMP100-Q1 and TMP101-Q1 devices is the chip itself. Thermal paths run
through the package leads as well as the plastic package. The package leads provide the primary thermal path
because of the lower thermal resistance of the metal. The GND pin of the TMP100-Q1 or TMP101-Q1 is directly
connected to the metal lead frame, and is the best choice for thermal input.

The TMP101-Q1 device features one address pin and an ALERT pin, allowing up to three devices to be
connected per bus. Pin logic levels are described in Table 7-3. The address pins of the TMP100-Q1 and
TMP101-Q1 devices are read after reset or in response to an I2C address acquire request. Following reading,
the state of the address pins is latched to minimize power dissipation associated with detection.

occurs on the bus. Upon receiving the STOP condition, the TMP100-Q1 and TMP101-Q1 devices switch the
input and output filter back to fast-mode operation.
7.3.10 POR (Power-On Reset)
The TMP100-Q1 and TMP101-Q1 devices both have on-chip, power-on reset circuits that reset the device to
default settings when the device is powered on. This circuit activates when the power supply is less than 0.3
V for more than 100 ms. If the TMP100-Q1 and TMP101-Q1 devices are powered down by removing supply
voltage from the device, but the supply voltage is not assured to be less than 0.3 V, TI recommends issuing a
General Call reset command on the I2C interface bus to ensure that the TMP100-Q1 and TMP101-Q1 devices
are completely reset.
7.3.11 Timing Diagrams
The TMP100-Q1 and TMP101-Q1 devices are Two-Wire, SMBUs, and I2C interface-compatible. Figure 7-3 to
Figure 7-6 describe the various operations on the TMP100-Q1 and TMP101-Q1. The following list provides bus
definitions. Parameters for Figure 7-3 are defined in the Timing Requirements table.
Bus Idle: Both SDA and SCL lines remain HIGH.
Start Data Transfer: A change in the state of the SDA line, from HIGH to LOW, while the SCL line is HIGH,
defines a START condition. Each data transfer is initiated with a START condition.
Stop Data Transfer: A change in the state of the SDA line from LOW to HIGH while the SCL line is HIGH
defines a STOP condition. Each data transfer is terminated with a repeated START or STOP condition.
Data Transfer: The number of data bytes transferred between a START and a STOP condition is not limited and
is determined by the controller device. The receiver acknowledges the transfer of data.
Acknowledge: Each receiving device, when addressed, is obliged to generate an Acknowledge bit. A device
that acknowledges must pull down the SDA line during the Acknowledge clock pulse in such a way that the
SDA line is stable LOW during the HIGH period of the Acknowledge clock pulse. Setup and hold times must be
taken into account. On a controller receive, the termination of the data transfer can be signaled by the controller
generating a Not-Acknowledge on the last byte that is transmitted by the target.

within the shortest possible time interval. To maintain accuracy in applications that require air or surface
temperature measurement, care must be taken to isolate the package and leads from ambient air temperature. A
thermally-conductive adhesive is helpful in achieving accurate surface temperature measurement.
8.2.3 Application Curve
Figure 8-3 shows the step response of the TMP100-Q1 and TMP101-Q1 devices to a submersion in an oil bath
of 100°C from room temperature (27°C). The time constant, or the time for the output to reach 63% of the input
step, is 0.9 s. The time-constant result depends on the PCB that the TMP100-Q1 and TMP101-Q1 devices are
mounted. For this test, the TMP100-Q1 and TMP101-Q1 devices are soldered to a two-layer PCB that measures
0.375 inch × 0.437 inch.

10.1 Layout Guidelines
Place the power-supply bypass capacitor as close as possible to the supply and ground pins. The recommended
value of this bypass capacitor is 0.01 μF. Additional decoupling capacitance can be added to compensate for
noisy or high-impedance power supplies. Pull up the open-drain output pins SDA , SCL, and ALERT (TMP101-
Q1) through 5-kΩ pullup resistors.
