Overview
The TMP451 is a high-accuracy, low-power remote temperature sensor monitor with a built in local
temperature sensor. The remote temperature sensors are typically low-cost discrete NPN or PNP
transistors, or on-die transistor or diode structures that are an integral part of microprocessors,
microcontrollers, or FPGAs. The temperature accuracy is ±1°C for the local and the remote temperature
sensors. The two-wire serial interface accepts SMBus communication protocol. The module and GUI are
designed to provide the user a quick setup to evaluate the system and register map with simply a few click
powered by GUI Composer. The EVM features perforations that allows the temperature sensor,
microcontroller, and remote BJT to be isolated and be connected to external systems.

TMP451EVM Hardware Overview and Setup
This section describes the set up and some of the hardware features present on the TMP451EVM.
WARNING
Many of the components on the TMP451EVM are susceptible to
damage by electrostatic discharge (ESD). Customers are advised
to observe proper ESD handling precautions when unpacking and
handling the EVM, including the use of a grounded wrist strap at
an approved ESD workstation.
2.1
Board Connectors and Components
Figure 2-1 shows the top side of the TMP451EVM. Highlighted are the USB connector, breakouts,
TMP451 device, and the remote BJT. The USB connector is directly plugged into the computer for power
and communication from the computer to the USB2ANY mircocontroller. The breakouts are where the
perforations are to break off each section to connect to external systems. Headers can also be soldered to
the vias to be used as test point and are positioned 100 mils apart to be compatible with a standard
breadboard.
Figure 2-1. TMP451EVM Board Top Side
2.1.1 EVM Power Supply Input – J1
J1 is the USB connector and is used to connect the PC. The interface is used to access the device’s
registers and read the conversion data from the TMP451 through I2C communication protocol.
TMP451EVM uses the +5-V input power supply of the USB connector to power the EVM. The EVM does
not require an external power supply. The board is powered by the USB port and provides switched +5 V

2.1.2 Pushbutton Switch – SW1
The SW1 push button is to bring the MSP430 into a BSL mode for upgrading the firmware with
combination of the USB connector. Press and hold the switch SW1 next to the USB connector while
plugging the USB cable from the board to the PC to bring the MSP430 into BSL mode.
2.1.3 LEDs-D3,5,6
D3 is a green LED that is used to indicate that the EVM has power and should turn on after plugging in
the board. D5 is used to indicated a THERM fault and will turn on when the device detects a THERM fault
and bring the pin LOW. D6 does the same function but for the ALERT/THERM2 pin. Both these LEDs are
red.
2.1.4 Remote BJT - Q1
Q1 is a MMBT3904LP NPN BJT. This is used as the remote temperature sensor on the EVM. The
MMBT3904LP typically has an N-factor of about 1.0042. Since the TMP451 assumes an N-Factor of
1.008 this can cause temperature error in the remote temperature reading. The GUI automatically sets the
N-Factor correction register to 1.0042 to compensate for this. If the device is reset it will set the N-Factor
correction register back to the default value or 1.008 and some temperature error may be seen. If remote
temperature error is seen please use the N-Factor correction feature to adjust the temperature reading.
The MMBT3904LP can also be broken off to allow for a different temperature remote to be connected.
2.2
Hardware Setup
The TMP451EVM hardware consists of the USB2ANY Platform and the TMP451 altogether in one single
board. The unit is easily connected through USB connector into the computer as shown in Figure 2-2. The
green LED (D3) should turn on after connecting to the computer, confirming the EVM is powered.
