    Hello Jian,

    Reading the voltage level of the TS2 pin should tell if the part is in shutdown or not.

    While the device is in SHUTDOWN mode, a ≈5 V level is provided at the TS2 pin with high source impedance. (note that in some cases it will be about 3V due to the high impedance of the TS2 pin, but still shutdown). During normal operation, the TS2 pin should read close to 0V
