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. |
