EVM User's Guide: ISOTMP35BEVM
ISOTMP35 Evaluation Module
Description
ISOTMP35
is the industry's first isolated temperature
sensor IC, and provides an analog output voltage
proportional to Centigrade temperature with a 10
mV/°C positive slope gain. This user's guide details
through the steps to operate the
evaluation module, designed to evaluate the isolated
temperature sensor. ISOTMP35BEVM also features a
detachable breakable ISOTMP35 temperature sensor
board portion and a screw hole for easy attachment to
a high-voltage bus bar or power MOSFET.

The sensor section can be separated from the microcontroller section. Then, the sensor side of the EVM must be reconnected to the microcontroller side to operate the ISOTMP35 in a high temperature or high voltage environment. The EVM has a bottom-side copper plate that can be glued or screwed onto a high voltage heat source for easy user evaluation. - Page 3 Evaluation Module Overview 1.5 General Texas Instruments High Voltage Evaluation (TI HV EVM) User Safety Guidelines WARNING Always follow TI’s setup and application instructions, including use of all interface components within their recommended electrical rated voltage and power limits. Always use electrical safety precautions to help make sure your personal safety and those working around you.

- Page 5 The ISOTMP35BEVM includes LEDs to indicate the board status; the green LED D3 illuminates when voltage is supplied to the 3.3V net. The 3.3V net is connected directly to pin 1 of the ISOTMP35. U1 is the onboard regulator which supplied the 3.3V net, and is enabled and disabled by switch S1. For normal operation of the EVM, S1 must be enabled.

On the sensor breakout board, R15 and C20 can be used for an optional RC circuit to filter the voltage output of the ISOTMP35. R15 is already installed on the board, but is a 0 Ohm jumper so acts as a short. C20 is not installed by default. -

Software 3 Software The ISOTMP35BEVM software allows a user to read temperature from the ISOTMP35 by using the MSP430F5528. The analog output voltage is read by the microcontroller and converted to displayed temperature in software. Once the EVM hardware is connected to the GUI, temperature is sampled automatically once the user navigates to the Data Capture tab. - Page 8 The SAVE START and SAVE STOP buttons enable the user to log the EVM temperature results in a .csv file. When SAVE START is selected, the file begins downloading, and downloading ends when SAVE STOP is selected.
