Features

 An ultra-fine CMOS process has been adopted for low power consumption in a

design with no charge-pump.

 A small 32-pin WLBGA package (ball pitch of 0.4mm/t=0.64mm) has been

adopted.

 1ch/2ch and 3ch/4ch are capable 1-2 phase (100) stepper drive, 16, 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.

 The input terminal is compatible with 1.8V system.

 Built-in 2 PI driver channels

 Built-in 2 Comparator channels

 Built-in low-voltage malfunction prevention and thermal shutdown circuit
