5 / 7 page LB11685VH Pin Function Pin No. Pin name Function Equivalent circuit 16 12 14 UOUT WOUT VOUT Each output pin of three phases. 20 PGND GND pin in the output part. This pin is connected to GND. The SGND pin is also connected to GND 9 RF Pin to detect output current. By connecting a resistor between this pin and VCC, the output current is detected as a voltage. The current limiter is operated by this voltage. 21 MCOM Motor coil midpoint input pin. The coil voltage waveform is detected based on this voltage. 22 SGND Ground pin (except the output part) This pin is connected to GND. The PGND pin is also connected to GND. 23 FG FG out made by back EMF pin. It synchronizes FG out with inverted V-phase. When don’t use this function, open this pin. 25 RD Motor lock protection detection output pin. Output with L during rotation of motor. Open during lock protection of motor (High-impedance). When don’t use this function, open this pin. 27 VCO PLL output pin and VCO input pin. To stabilize PLL output, connect a capacitor between this pin and GND. 1 CX VCO oscillation output pin. Operation frequency range and minimum frequency are determined by the capacity of the capacitor connected to this pin. Pin No.9 Pin No.20 Pin No.16,14,12 Pin No.21 SGND SGND SGND VCC VCC SGND SGND Pin No.23 No.25 SGND SGND Pin No.27 VCC SGND SGND VREG VREG VREG Pin No.1 VCC SGND SGND VREG Continue to the next page.
