Pin function
• W-phase Hall-effect input pin.
W+>W– is established when logic is at an high level.
• V-phase Hall-effect input pin.
V+>V– is established when logic is at an high level.
• U-phase Hall-effect input pin.
U+>U– is established when logic is at an high level.
• Minus pin for Hall-efffect bias,
When stopped, switches open and Hall-effect bias
severs.

• Frequency characteristics revision pin. By installing a
capacitor between this pin and GND, close-loop
oscillation for the current control system halts.
• Index input pin.
When the I+ pin is at an low level, I1 operates with the
fixed current of I1=10µA and when at an high level, I1
does not flow.
Hysteresis width is determined by the resistor attached
externally to the I+ pin.
• Time changeover pin.
