    Hi,

    1. No soft switch is needed. Please refer to 8.2.6.3 Supplement mode on the d/s.
    2. The device may operate with VBUS only, or VBAT only or with both VBUS and VBAT. The boost (OTG) operation can be enabled if the conditions described in 8.2.5 Boost Mode Operation from Battery on the d/s are valid.
    3. The device continuously monitors battery temperature by measuring the voltage between the TS pin and ground. Please refer to 8.2.7.5 Thermistor Qualification on the d/s.

    Thanks,

    Ning.
