8 / 9 page LB1996 No. 5977-8/9 Pin number Pin name Pin voltage Equivalent circuit Pin function 21 2V to 3V 22 23 24 PWR GND 1 2 5R F 19 C C 16 BRAKE Continued from preceding page Control reference voltage supply pin. Determines control start voltage. Speed control voltage supply pin V type control technique VC > VCREF : Forward VC < VCREF : Slowdown (Reverse-blocking circuit prevents reverse rotation.) W phase output Output transistor GND V phase output Upper side output NPN transistor collector pin (common for all 3 phases). For current detection, connect resistor between VCC3 pin and RF pin. Constant current control and current limiter works by detecting this voltage. 3 Hall FG/1 Hall FG switching pin FGSEL High –> 3 Hall FG Low/Open –> 1 Hall FG Short brake pin BRAKE: High –> Short brake operation Low/Open –> Motor drive operation U phase output VCREF VC WOUT VOUT UOUT 0V to VCC1 22 25 µA 100 µA 100 µA 25 µA VCC1 200 Ω 10k Ω 15k Ω 30k Ω 30k Ω 200 Ω 21 5 24 VCC2 3.9 Ω 3.9 Ω 23 1 2 19 VCC1 50k Ω 75k Ω 100 µA 16 VCC1 50k Ω 75k Ω A11177 A11178 A11179 A11180 FGSEL |
