• Negative potential that provides Hall
• Output transistor ground
• FG amplifier output
• FG amplifier minus input
• FG amplifier plus input
A 2.5 V reference voltage is generated
internally by the IC.
• Index inputs
• U-phase Hall device inputs
• V-phase Hall device inputs
• W-phase Hall device inputs
• Index timing adjustment voltage input
device bias current
In the stopped state, this pin is set to the
open state to cut off the Hall device bias
current.
