Truth Table
Note: The Hall input "H" and "L" values are defined as follows: "H" means that for that phase the (+) input is higher than the (-) input, and "L" means that for
that phase the (+) input is lower than the (-) input. However, note that an input potential difference corresponding to the Hall to output gain is required.
Timing Charts
Note: The Hall inputs are defined as follows: U = UIN1 – UIN2, V = VIN1 – VIN2, and W = WIN1 – WIN2.
Inputs to the Hall input pins must be applied in the phase order shown in the timing chart.
