室温25度测试1.2V供电为510mA， 室温升到85度时，1.2V供电变为670mA。此时IC Tj=120度。
请问下为什么高温下1.2V电流会上升？ 能否通过软件或其他设置控制其恒定，以降低结温。

你好，
回复如下：
150mA current increase at high temperature is completely normal, and similar to what we have seen in characterization.
The Tj is going to be directly related to the power consumption and the heat sinking capabilities of the board. In order to reduce Tj you will need to either reduce the power consumption of the device or increase the heat sinking capabilities of your PCB/system. You can lower the duty cycle, reduce the number of tx/rx, reduce tx output power, etc in order to reduce the overall device power consumption. We do not have any custom software designed to reduce the Tj, this will need to be done by modifying their sensor configuration and/or PCB.
