Features
 CMOS process adoption and 1ch-4ch using D class amplifier to achieve low
power consumption.
 A small 40-pin QFN package 5mm x 5mm, t=0.80mm (max) is used.
 Built-in autonomous drive circuit controlled by serial settings (self propelled
control)
 1ch/2ch and 3ch/4ch are capable of 2-2 phase stepper drive, 1-2 phase
(100%) stepper drive, 1-2 phase (70%) stepper drive and 256/512/1024
resolution micro-steps.
 3ch/4ch is capable of constant voltage drive.
 5ch is capable of constant current drive and FLL control.
 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 2 comparators and 1 Schmitt buffer.
 Built-in low-voltage malfunction prevention and thermal shutdown circuit.
 Power supplies VCC and VM are internally isolated and inc
