急!!!!!!!!!!!!!!!LM3424 热保护问题

Other Parts Discussed in Thread: LM3424

Ti engineer,

我在使用LM3424做温度保护时,有一点不理解,请帮忙解释一下,AN-1969 LM3424 Boost Evaluation Board

1. 评估板说用100k的NTC,为何RNTC-BK会等于243K呢,RNTC-END=71.5K?

2.RNTC-BK和RNTC-END和NTC有什么关系?

Using a standard 100k NTC thermistor (connected to pins 4 and ll), find the resistances corresponding to
TBK and TEND (RNTC-BK = 243 kΩ and RNTC-END = 71.5 kΩ) from the manufacturer's datasheet. Assuming RREF1
= RREF2 = 49.9 kΩ, then RBIAS = RNTC-BK= 243 kΩ.
