Overview
The R2A30444BX is a semiconductor integrated circuit that incorporates driver
circuits suitable for motor of digital cameras.
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.
