2.2 EVM Operating Conditions

The TMP4718EVM power is supplied through the USB connector. The LDO converts the 5 V from the USB to 3.3 V used by the TMP4718 and the MSP430. The EVM may be directly inserted into a USB port on a PC or laptop, or may be connected to the latter using an appropriate USB cable. The controller and device sides of the EVM have different temperature limits as shown in #GUID-590F18A0-08F4-470E-9253-17933312E322/GUID-B7FD9CA8-FE98-4BCB-96DE-37F2A08B4448. These temperature limits are set by the onboard MSP430 on the controller and the TMP4718 ICs on the breakout points.
