Datasheet 40 V Stepping Motor Driver BD63401EFV General Description Key Specifications BD63401EFV is a bipolar low-consumption driver that Range of Power Supply Voltage 8 V to 33 V driven by PWM current. Rated power supply voltage of Rated Output Current 1.35 A the device is 40 V, and rated output current is 1.35 A. Range of Operating Temperature -25 C to +85 C PARA-IN driving mode is adopted for input interface. In Output ON Resistance 1.0 (Typ) addition, the power supply can be driven by one single (total of upper and lower resistors) system, which simplifies the design. Package W (Typ) x D (Typ) x H (Max) Features HTSSOP-B20 6.50 mm x 6.40 mm x 1.00 mm Rated Output Current 1.35 A Low ON Resistance DMOS Output PARA-IN Drive Mode PWM Constant Current (other oscillation) Built-in Spike Noise Cancel Function (external noise filter is unnecessary) FULL STEP, HALF STEP Functionality Current Decay Mode is SLOW DECAY Power Save Function Built-in Logic Input Pull-down Resistor Thermal Shutdown Circuit (TSD) Over-current Protection Circuit (OCP) Under Voltage Lock Out Circuit (UVLO) Over Voltage Lock Out Circuit (OVLO) Protects against malfunction when power supply is Typical Application Circuit disconnected (Ghost Supply Prevention function) Microminiature, Ultra-thin and High Heat-radiation (exposed metal type) Package TEST Application Sewing Machine, PPC, Multi-function Printer, Laser IN1 Beam Printer, Ink-jet Printer, Monitoring Camera, IN2 PS WEB Camera, Photo Printer, FAX, Scanner, Mini IN3 Printer, Toy and Robot IN4 VCC1 VREF1 OUT1A VREF2 OUT1B RNF1 VCC2 OUT2A SELECT TIMING OUT2B RNF2 GND Product structure : Silicon integrated circuit This product has no designed protection against radioactive rays www.rohm.com TSZ02201-0P2P0C702100-1-2 2018 ROHM Co., Ltd.
