我使用 IC BQ25180开发了一个 PCB。

所用电路如下图所示。 (VBUS 由 USB 提供)

我通过 I2C 进行通信、并在电路板初始化时使用以下值设置寄存器：

    ESP_LOGI(TAG, "Registers defined to custom configuration!");

}

在某个点、我会调用以下函数将其置于 SHIPMODE

void BQ25180_SetShipMode(bool enable) {

    BQ25180_Register_SHIP_RST registerSHIP_RST;
      
    if(true == enable) {       
        registerSHIP_RST.PB_LPRESS_ACTION = 0b01; // Pushbutton long press action = Hardware Reset
        registerSHIP_RST.EN_RST_SHIP = 0b10; // Enable shipmode with wake on button press or adapter insert
        
        ESP_LOGW(TAG, "Ship mode will be set to ON!");
    }
    else {

        registerSHIP_RST.PB_LPRESS_ACTION = 0b00; // Pushbutton long press action = Do nothing       
        registerSHIP_RST.EN_RST_SHIP = 0b00; // Do nothing      

        ESP_LOGW(TAG, "Ship mode will be set to OFF!");
    }

    BQ25180_WriteRegister(BQ25180_REGISTER_SHIP_RST, (uint8_t *)&registerSHIP_RST, sizeof(registerSHIP_RST));   
}

进入 SHIPMODE 时、芯片的行为如预期、输出电压被切断、功耗保持预期状态、但连接 VIN 后只能退出 SHIPMODE 模式。

您能告诉我我哪里出了问题吗？ 如果您有任何问题或必要的测试、我可以随时为您提供帮助。

我尝试更改 registerSHIP_RST 的值。 en_push 但未成功。
