    Hi,

    This is described in the device datasheet Section 10.4.2:

    • Write #1: [SHUT_A] = 0, [SHUT_B] = 1

    • Write #2: [SHUT_A] = 1, [SHUT_B] = 0

    For C examples, you can search sites like GitHub for many user code examples. For example, there is one project using BQ76930 here that includes a function for entering SHIP mode: https://github.com/mikethezipper/10s_Ti_BQ76930_BMS 

    When the device is in SHIP mode, the voltage on the REGOUT pin will go to 0V and you will no longer be able to communicate with the device. A rising edge on TS1 will return the device to NORMAL mode.

    Best regards,

    Matt
