10 / 15 page LB11993W No.A0677-10/15 Pin Description Pin No. Symbol Voltage Equivalent Circuit Diagram Description 50 49 48 47 46 45 UIN1 UIN2 VIN1 VIN2 WIN1 WIN2 0 to VCC1 Capstan motor driver U, V, and W phase Hall element input/output. IN1 > IN2 state for logic H 39 ANGLE Hall input/output gain control. Insertion of a resistor between this pin and ground controls the gain. 44 VS_C 0 to VCC2 Power pin that determines the amplitude of the outputs to the capstan motor. The voltage applied to this pin must be lower than VCC2. 54 52 51 53 UOUT_C VOUT_C WOUT_C Rf_C Capstan motor driver U, V, and W phase output. 42 VH+ 41 VH- Hall element bias voltage supply. A voltage that is typically 0.85V is generated between the VH+ and VH- pins (when IH= 5mA). 37 FGIN- FG comparator inverting input. There is no internally applied bias. 38 FGIN+ 0 to VCC1 FG comparator noninverting input. There is no internally applied bias. 36 FGOUT_C FG comparator output. There is an internal 20k Ω resistor load. 40 FRC_C 0 to VCC1 Capstan forward/reverse select pin. The voltage on this pin selects forward or reverse rotation. (with hysteresis) 19 STBY_C Pin to select bias supply to capstan circuits other than FG comparator. Setting this pin to low cuts-off the bias supply. Capstan motor standby pin.
