Positional signal abnormality protection
Low power supply voltage protection (V
high impedance outside the operating voltage range to prevent damage caused by power device
short circuits.
However, if the voltage level is supplied from the V
4.9 V is applied, low power supply voltage protection does not operate.
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
