特性 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
