关于电源的温度保护的问题.

有更好用的器件啊
比如TMP35等,给个5V电源,它在25度时输出250MV,75度时输出750MV,特别适合用于检测温度.大小和三极管一样,
当然价格比二极管高多了.

谢谢回复.不知这个多少钱啊.
它的DATSHEET上给的温度曲线是VIN=3.3V的,不知5V时,输出电压是多少?

谢了,这个多少钱一只?
DATASHEET上未给出5V时的电压输出的曲线,不知100度时,输出多少V

多少钱?
11

价格
力源的公开报价是八块多,别的地方批量能五块钱拿到吧.

工作电压范围2.7到5.5V
输出电压只跟随温度都一样

why not use the ICs with built in over temperature protection function. It seems the price is little bit high, but the system cost is much lower since the componenet you guys are talking about is much more than the IC itself. Why do you save 1 cent on the IC and spend 1 dollar on the compoenets to design for the function the other ICs alraedy built in?
Any comments are welcame.
