Notes 1. This IC has a circuit that prevents current from flowing into the VM pin when VDD = 0 V.

2. The motor current accuracy varies depending on the motor actually used. With this IC, the total of the

reference voltage VREF error and the current sense circuit error is within ±10%.

3. Current setting parameter for address 3, address 4, address 7, address 8 and address C.
