0017 Description
0018 -----------
0019
0020 This driver implements support for Maxim MAX31730.
0021
0022 The MAX31730 temperature sensor monitors its own temperature and the
0023 temperatures of three external diode-connected transistors. The operating
0024 supply voltage is from 3.0V to 3.6V. Resistance cancellation compensates
0025 for high series resistance in circuit-board traces and the external thermal
0026 diode, while beta compensation corrects for temperature-measurement
0027 errors due to low-beta sensing transistors.
