Other Parts Discussed in Thread: BQ24072, BQ24075, BQ24075T, BQ24072T, BQ24079T, BQ24079
您好！
我在使用BQ24073时，其中PIN1接到电池的NTC，电池的NTC阻值为10K，现在实际测试在高温环境下，电池的充电截止温度为57°C，我们现在期望的充电截止 温度是45°C，想请问下可以从哪些方面做调整？目前我们的电路设计如下图：
烦请帮忙解答，谢谢！
您好,请参考下面内容:
The BQ24073 uses a current based NTC monitoring system which makes it difficult to change to 0C to 45C, even with resistors in series or parallel to the NTC resistor. What Varta can do is switch to the BQ24072T, BQ24075T, or BQ24079T (T versions of the BQ24072, BQ24075, and BQ24079 respectively).
I've got a more detailed explanation on their differences here: [FAQ] BQ24072T: What are the differences between the BQ24072T and the BQ24072
You can then add resistors to adjust the temperature threshold based on the desired RNTC HOT and COLD values
