1 / 21 page  1 RT8750 DS8750-01 April 2011 www.richtek.com Ordering Information Note : Richtek products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes. 4+2 CH Motor Driver for DSC General Description The RT8750 is a 4+2 (two exclusive control modes) channel motor driver for DSC application. In total, it provides 4+1 full swing channels, 3+1 constant voltage channels, and 1 constant current channel. It includes dedicated control mode for stepping motors in 1-2 phase or 2-2 phase operation. The RT8750 also provides two photo-interrupters for motor position detection. The RT8750 can be controlled via 3 parallel input ports and a serial input interface. The voltage setting of the constant voltage drivers and the current setting of the constant current driver can be configured by 4-bit DACs via serial input interface. Other features include UVLO, thermal shutdown, power save mode, and software reset. Hence, the RT8750 can cover most of the motor applications in a DSC system. The RT8750 comes in a small WQFN-20L 3x3 package to save board space.
