| 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. |
