产品概述

The MAX31730AUB+ is a 3-channel remote temperature sensor in 10 pin µMAX package. It monitors its own temperature and temperatures of three external diode connected transistors. The operating supply voltage is from 3V to 3.6V. Resistance cancellation compensates for high series resistance in circuit board traces and external thermal diode while beta compensation corrects for temperature measurement errors due to low beta sensing transistors. All temperature channels have programmable temperature thresholds. A status bit is set in thermal status registers and open drain THERM output asserts when measured temperature of channel crosses respective threshold. The 2-wire serial interface accepts SMBus protocols (write byte, read byte, send byte & receive byte) for reading temperature data and programming temperature thresholds.
  • Accurate temperature measurement helps designers meet error budgets
  • Operating temperature range from -40°C to 125°C
  • Supply current of 2.5µA (standby) and 700µA (operating)
  • Highest temperature register simplifies and speeds overtemperature notification
  • 12bit, 0.0625°C resolution and programmable temperature thresholds
  • Remote temperature accuracy of ±2.5°C at TA = -40°C to +125°C, TRJ = -40°C to +125°C
  • -64°C to 150°C remote temperature measurement range, ±2°C local temperature accuracy (-40 to 125°C)
  • Resistance cancellation for remote channels and compensation for low beta transistors
  • One local and three remote temperature sensing channels
