BQ76952: Modify CUV value during operation

Che Liu

Part Number: BQ76952

Dear:

    We want to achieve this function: modify the protection threshold of CUV during operation. 

    After the modification, the original protection value is used for the first protection, and the new protection threshold is used after the fault is restored.
    How to design to realize that the first protection after modification is the new protection value?

    Looking forward to your reply.

    Hi,

    Unfortunately, changing the register settings is not easy during operation. To change a register value, you must enter CONFIG_UPDATE mode. In this mode the FETs are disabled. The new settings take effect after sending the EXIT_CFG_UPDATE() command. 

    Best regards,

    Matt
