- Description
- -----------
- This driver implements support for Maxim MAX31730.
- 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.
