Domestic Chip List: Xin Xin recommended Shengbangwei SGM4056 for power supply. Have you used it? What do you think? [Copy link]

 

The best site for domestic chips, I received a recommendation for Shengbangwei SGM4056 for charging management. Have you used it? What do you think? Come and post your comments

Recommender: @辛昕

Recommended product model: SGM4056

推荐理由:说到国产模拟芯片,或者电源芯片,怎么能不提到圣邦微呢?实际上,早在以华为被禁为一个全面标志性事件发生“美国真的可以无耻到掐我们芯片脖子逆全球化行径”以前的2016、7年,其实我就是因为看到我们公司的产品原理图上频频出现SGM系列的电源管理芯片——这才让我开始觉得,哦,原来现在,在电源芯片上(主要是LDO、DCDC等),已经有了一个不错的国产替代选择因为我虽然懂电路,简单的外围电路我甚至可以自行设计,但是我并非职业的硬件工程师,没有做过真正意义上的产品级硬件设计。所以,当我眼看着自己经历的一家又一家的公司,开始使用SGM这个前缀的芯片的时候,当我查到它是国产芯片圣邦微的时候,国产芯片的使用——那时候还谈不上国产替代,对我来说,至少,在模拟领域,是从圣邦微开始的。这款SGM4056型号,其实我已经几乎想不起来了,我只记得是一个电源芯片,却不记得到底是LDO还是DCDC。其实,当时我们一个板子上的电源芯片,往往不止一块:降压的(MCU系统往往有好几个不同电压值,从主电12V先到5V,再到3.3V,再到1.8V),各级的降压型DCDC芯片,当然也少不了锂电池充电、保护等......所以很多时候,我们一个板子上用了不止一块SGM芯片虽然后来,我因为股市和国产替代这个大背景,开始关注国产模拟芯片,届时,我才知道,圣邦微,一度被称为国产模拟芯片第一股,或说,即使在上市公司这个光环之外,它也至少是最早出现在大多数用户眼前的那个国产模拟芯片......然而我刚看了一眼,在和电源有关的领域,居然提都没提到圣邦微,这怎么行呢?

Shengbang Weibo has too few followers. You can try it next time if it is useful.
