bq76930怎么从SHIP Mode切换回到NORMAL Mode?

时间:10-02 整理:3721RD 点击:

从NORMAL Mode切换到SHIP Mode后,按TS1激活和对地址0x04写入0x00都好像回不到NORMAL Mode,从bq76930读出来的电压数据始终不对,想请问怎么才能回到NORMAL Mode,回到初始激活的正常工作状态。

ship 模式就是芯片完全shutdown的状态,就是需要重新激活, 没有其他方法。 

To get the part of SLEEP into Active mode, the bq76930 requires an external "wake pulse" (>1V))on the TS1 Pin on the bottom group. The boot sequence and the voltage after the BOOT on TS1( >1V)--CAP1--> REGOUT--SCLK-->CAP2--CAP3.

For the device to be commanded via the I2C into SLEEP mode by the controller; The device needs a 2 register write [SHUT_A, SHUT _B]= [0,1], [SHUT_A, SHUT _B]= [1,0]
