Overview
The R2A30440NP is a semiconductor integrated circuit that incorporates driver circuits suitable for motors in digital cameras. The terminal arrangements are basically identical to that of R2A30423NP.
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...
