Features
 An ultra-fine CMOS process has been adopted for low power consumption in a
design with no charge-pump.
 A small 36-pin WLP package (ball pitch of 0.4mm/t=0.60mm) has been adopted.
 1ch/2ch and 3ch/4ch are capable of 2-2 phase stepper drive, 1-2 phase (100%)
stepper drive, 128, 256 and 512 resolution micro-steps.
 3ch/4ch is capable of constant voltage drive.
 5ch/6ch is capable of constant current drive.
 By using exclusive control mode on 5ch and 6ch, it resembles 7ch drive.
 Built-in 3 PI drivers channels.
 Built-in 3 Schmitt buffers channels.
 Built-in low-voltage malfunction prevention and thermal shutdown circuit.
 Power supplies VCC and VM are internally isolated and include a function to
prevent reverse current between the power supplies.
