What are the Auto Selection and Manual Selection modes?

The TCK32 Series of load switch ICs (power multiplexers) provide the Auto Selection and Manual Selection modes, which allow selection between two power lines. In Auto Selection mode, the TCK32 Series determines whether V_INA and V_INB are within the normal voltage range and automatically passes whichever is at a normal input voltage to the output. When both V_INA and V_INB are within the normal voltage range, V_INA is given precedence. In Manual Selection mode, the TCK32 Series selects either V_INA or V_INB according to the signal applied to the V_SEL terminal.
