7 / 10 page No. 6213-7/10 LB11817 Pin No. Symbol Pin voltage Function Equivalent circuit 8 GND Continued on next page. 4.2 to 6.5 V 9 VCC • Supply voltage This voltage must be stabilized so that ripple and noise do not enter the IC. VCC + 1.55 Vtyp (Ip = –5 mA) 10 VP • Boosted voltage output Used as the output transistor pre-driver power supply. This boosted voltage is used when a low saturation output is provided. In all other cases this pin will be at the VCC potential. 11 RF • Output current detection An RF resistor inserted between this pin and VCC converts the output current to the voltage used for output current detection. The current limiter circuit operates by detecting the voltage on this pin. 12 15 D2 D1 VP VCC 15 12 • Connections for the two diodes used by the voltage boost function. 13 14 17 19 20 B2 B1 WOUT VOUT UOUT • W-phase output • V-phase output • U-phase output 20 17 19 11 18 • Boost function switching circuit outputs 1 and 2 Continued from preceding page. • Ground This pin and pin 34 must all be connected to the frame ground.
