MAX31730

MAX31730 EVALUATION KIT AVAILABLE 3-Channel Remote Temperature Sensor General Description The MAX31730 temperature sensor monitors its own temperature and the temperatures of three external diodeconnected transistors. The operating supply voltage is from 3.0V to 3.6V. Resistance cancellation compensates for high series resistance in circuit-board traces and the external thermal diode, while beta compensation corrects for temperature-measurement errors due to low-beta sensing transistors. All temperature channels have programmable temperature thresholds. When the measured temperature of a channel crosses the respective threshold, a status bit is set in the thermal status registers and the open-drain THERM output asserts. A highest temperature register allows the master to obtain the temperature of the hottest channel. The 2-wire serial interface accepts SMBus protocols (write byte, read byte, send byte, and receive byte) for reading the temperature data and programming the temperature thresholds. Any one of eight available slave addresses can be selected using the address selection input (ADD), which can be connected to ground or connected to a grounded resistor. The MAX31730 supports 3.0V to 3.6V operation and is specified for a -40°C to +125°C operating temperature range. It is available in a 10-pin µMAX® and a 12-pin, 3mm x 3mm TDFN package.
