8 / 12 page  No. 6497-8/12 LB11975 Continued from preceding page. Pin No. Pin Pin voltage Function Equivalent circuit Control loop frequency characteristics correction Closed loop oscillation in the current control system can be stopped by connecting a capacitor between this pin and ground. 11 FC 11 10 VCC1 500 Ω 500 Ω 65k Ω 500 Ω 2k Ω VCC1 13 14 500 Ω 500 Ω 28 2k Ω 2k Ω VCC2 2 1 3 6 VCC1 VCC3 7 30 31 4 35 36 VCC1 300 Ω 12 11k Ω PWM oscillator capacitor connection 10 PWM Control reference voltage input The control start voltage is determined by this voltage. 13 VCREF 0 V to VCC1 – 1.5 V Speed control voltage input This IC implements a voltage control system in which VC > VCREF means forward rotation and VC < VCREF means slow foward rotation. (This IC includes reverse rotation prevention circuit, so reverse rotation will not occur.) 14 VCTL 0 V to VCC1 – 1.5 V W phase output 3, 4 OUT3 Ground for the output transistors 6, 7 30, 31 GND2 V phase output 1, 2 OUT2 U phase output 35, 36 OUT1 Upper side npn transistor collector (shared by all three phases) Connect a resistor between VCC3 and the RF pin for current detection. The fixed current control system and the current limiter operate by detecting this voltage. 28 RF Peak hold circuit capacitor connection. Connect a capacitor to this pin to smooth the voltage detected by the resistor RF. 12 PH |
