5 / 12 page No.8095-5/12 LB11693 Pin Functions Pin No. Symbol Function Equivalent circuit 28 1 2 OUT1 OUT2 OUT3 Motor drive outputs 3 GND2 Motor drive output system ground 4 VD Low side output transistor drive current supply 6 VM Motor drive output power supply and output current detection Connect the resistor Rf between this pin and VCC. The output current will be limited to the current value set by the equation IOUT = VRF/Rf. 1 2 28 300 Ω VM 3 6 VCC VD 4 5 VCC Power supply for systems other than the motor drive output 7 VREG 5 V regulator output Insert a capacitor (about 0.1 µF) between this pin and ground for stabilization. 7 VCC 8 LVS Undervoltage protection voltage detection To detect VREG, connect this pin to VREG. To detect VCC, set the detection voltage by inserting a zener diode in series. VREG 9.5 k Ω 52 k Ω 8 9 FGFIL FG filter connection This pin is normally left open. If noise on the FG signal is a problem, insert a capacitor between this pin and ground. VREG 300 Ω 9 Continued on next page. |
