Function
• U-phase Hall element input
• V-phase Hall element input
• W-phase Hall element input
• Minus-side pin for applying the Hall bias current
This pin goes to the open state in the stopped state
and the Hall bias is cut off.
• FG amplifier plus input
A reference voltage of 2.5 V is generated by the IC
internally.
• FG amplifier minus input
• FG amplifier output pin
