Stepping Motor Driver Series Standard 36V Stepping Motor Drivers No.12009EAT07 BD63801EFV Description BD63801EFV is rated 24V system maximum input voltage / 0.8A maximum output current and employs a constant-current PWM control scheme for low power consumption. Serial (CLK-IN) drive mode allows for simple interfacing and operation, while allowing for full and half excitation modes. The single-power supply configuration allows for easy design and layout in the application. Feature 1) Power supply: one system drive (19V28V) 2) Low ON resistance DMOS output 3) Serial (CLK-IN) drive mode 4) PWM constant current control (self oscillation) 5) Built-in spike noise cancel function (external noise filter is unnecessary) 6) FULL STEP applicable to HALF STEP 7) Normal / Reverse rotation switching function 8) Power save function* 9) Built-in logic input pull-down resistor 10) Power-on reset function 11) Thermal shutdown circuit (TSD) 12) Over current protection circuit (OCP) 13) Under voltage lock out circuit (UVLO) 14) Over voltage lock out circuit (OVLO) 15) Malfunction prevention at the time of no applied power supply (Ghost Supply Prevention) 16) Electrostatic discharge: 4kV (HBM specification) 17) Microminiature, ultra-slim and high heat-radiation (exposed metal type) HTSSOP package 18) Function pin compatible with constant current 2ch 36V Simple Stepping Motor Driver Series Application PPC, Laser beam printer, Scanner, Photo printer, FAX, Ink jet printer, Mini printer, Sewing machine, Toy, and Robot etc. www.rohm.com 2012.02 - Rev.A 1/8 2012 ROHM Co., Ltd.
