为什么昂宝的IC(OB226X)没有公开的Datasheet?
是不是有侵犯人家专利的嫌疑,因为按美国法律,只要资料不公开,即使侵犯专利也没有关系,听说它的产品和安森美有些瓜葛,请昂宝的人出来解释一下!!

估计SG也是被PI打怕了,所以也不公开了,那个美国法律也是听别人说的,也搞不清楚是不是这样.其实听过昂宝的研讨会,居然有一半的时间是说它们有各种专利.既然有专利,产品又批量生产了,为什么又不公开呢,不得不让人怀疑是心里有鬼.
You can ask OB disty and sales if you need. All OB products do have OB own Patents and some are already issued by US patent office. You will find out that all OB produts donot infringe any other patents after you study it.
The reason of not opening the datasheet to public is that there are many IC companies in China that copy everything from IC to datasheet. If you search you can find out that, for example, all SG's IC and datasheets are copied by a company in Chengdu. This is why OB does want to release the datasheet to public. OB wants to protect itself, and does not want to spend time to fight with those guys.

你说的也有一定道理,但是还是可以通过其他途径得到datasheet.想仿制也是一样容易,因为既然申请了IP,资料也就公开了.另外不管是NCPXXX,SGXXX,OBXXX,FSDXXX等等,说白了就是CMOS型3842,主要就是功耗下来了,再加一点额外功能把外围电路集成一下.
每家公司都会说自己有专利的,发布的专利也可能有问题,否则就不会有那么多官司了.

我想IC厂想拿到一份DATASHEET还不至于那么难吧?否则也不用做芯片了.
