The MAX31730 temperature sensor monitors its own temperature and the temperatures of three external diode-connected 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 active-low 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 and is available in a 10-pin µMAX® and a 12-pin, 3mm x 3mm TDFN package.ApplicationsCommunications EquipmentCPU, FPGA, and ASIC Die Temperature MonitoringServers

The MAX34417 is a specialized current and voltage monitor used to determine power consumption of portable systems. The device has a very wide dynamic range (20,000:1) that allows for the accurate measurement of power in such systems. The device is configured and monitored with a standard I2C/SMBus serial interface. The unidirectional current sensor offers precision high-side operation with a low full-scale sense voltage. The device automatically collects the current-sense and voltage samples and then multiplies those values to obtain a power value it then accumulates. Upon a command from the host, the device transfers the accumulated power samples, as well as the accumulation count, to a set of registers accessible by the host. This transfer occurs without missing a sample and allows the host to retrieve the data not in real-time, but at any time interval. Watch video: Introducing the MAX34417 Evaluation KitApplicationsServersSmartphonesTabletsUltra Notebooks
