Internal protection

 Positional signal abnormality protection

Output is turned off when the positional signal is HHH or LLL; otherwise, it is restarted.

For power supply on/off outside the operating voltage range, the turn-on signal output is kept at

high impedance outside the operating voltage range to prevent damage caused by power device

short circuits.

4.9 V is applied, low power supply voltage protection does not operate.
