BQ76952: 引脚使用详情

您好

1, BAT 推荐使用推荐的电路。您可以参考下面帖子的内容

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/934744/bq76952-disconnecting-bat-power-input

2，初始化就是正常模式

3，VC0与VSS电路建议参考评估板的电路.

4, 是单独控制充放电MOS，你可以参考

•  Multiple FETs with the BQ76952, BQ76942 Battery Monitors (Rev. A). 
• This video also briefly covers reverse charging configuration and shows more schematic development information: Creating the Schematic for BQ769x2 Battery Monitors - YouTube.

5，PCHG PDSG请参考下面帖子的内容

6，DCHG and DDSG请参考下面帖子内容

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1209683/bq76952-bms-with-bq76952-functionality-of-dchg-ddsg-in-the-afe?tisearch=e2e-sitesearch&keymatch=BQ76952%20DCHG%20DDSG#

7，PACK pin should be connected to BAT+ with a 10k pull-up resistor.

8，Using the REG1/REG2 regulators is not required. Many users use these to power the MCU or other electronics in the system. 

If you are not using BREG, REGIN, REG1, REG2, see Table 16-3 in the datasheet for instructions on how to connect these pins. All four pins can be tied to VSS if unused.

9，BQ76952 can operate standalone, but this requires programming the desired settings into OTP. This thread has some helpful guidance on OTP programming in addition to the information in the TRM: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1082914/faq-bq76952-common-questions-for-otp-programming-with-the-bq769x2-device-family

关于问题3，如图所示

- PCB上VC0已经通过串联电阻与VSS相连（如图中标出的B走线）

安装顺序为：

step1 图中A点先连接（此时VSS悬空，没有与cell1负极相连）

step2 连接器J1插入PCB（随机顺序上电）

请问这个情况是符合要求的吗？

您好，正在询问更了解这款芯片的TI工程师，稍后回复。

好的，感谢您的解答！
