BQ24040充电问题

Other Parts Discussed in Thread: BQ24040

Dear Engineer,

1、BQ24040的TS脚除了接一个10K的电阻到Vss,使之disable外,是否就只能接10k NTC热敏电阻(103AT)?是否可以换成其他的NTC?

                 BQ24040规格书:

                 9.2.1.2.1.3 TS Function (bq24040)

                           Use a 10k NTC thermistor in the battery pack (103AT).

                           To Disable the temp sense function, use a fixed 10k resistor between the TS (terminal 1) and Vss.

2、TS接10k NTC热敏电阻,它的充电温度范围是否只能在0~60℃?能否改到0~45℃范围内充电?是否有什么建议?

3、BQ24040在开始充电时,输入电流会有十几秒的波动,检测TS脚的电压也会有波动,这个是否会与TS 的layout有关?有什么改动layout的建议吗?
