No.A0375-6/7 LA5688H Cautions for Use (1) GND1 and GND2 When using, short-circuit GND1 and GND2 externally. (2) Supply voltage when only the motor driver is used without using the regulator As the reference power supply in IC is taken from VCC1, apply the voltage also to VCC1. In this case, the operation condition of VCC1 ranges from 3.5 to 7.5V. (Refer to page 2. Operation Conditions, Supply Voltage 1') (3) Supply voltage when only the regulator is used without using the motor driver The regulator operates with VCC1 (without need of applying voltage to VCC2, VCC3, and VREF) (4) VREF pin Application of the voltage to VREF pin enables setting of each OUT Hi voltage. In this case, the input to VREF ranges from 0.3 to (VCC3-1) V. (Refer to page 2.
