BQ25895M PMID相关问题

TI的专家,

针对BQ25895M的应用部分，需要用到Boost Mode。有如下疑问:

1.PMID是否可以作为类似DCDC的功能来给其它电路供电？

2.PMID是否可以设定固定的5V(或其它电压)

3.当应用的产品是有线+无线功能，如何实现有线(USB供电)和无线(锂电池供电)互相切换时，PMID都能输出固定的5V(或其它电压)?

Star Xu：

The 5V output is from the PMID pin when no input power is available and the battery is providing power to the buck converter, which is operating in reverse as a boost converter. The SYS output equals the following:
2a)Only My Adpter in put is connected , No Battery Connected – 4.2V

2b) Only Battery is connected , No Apter input is there – BATTERY VOLTAGE

2c) Both Adapter and Battery is connected. – MINSYS (user selected 3.0V to 3.7V) the follows the battery voltage up to 4.2V
