Stepping Motor Drivers
BD63940EFV, BD63960EFV
No.12009EAT11
●Description
BD63940EFV,BD63960EFV are the ultra simple type that provides the minimum function for driving stepping motor and
various protection circuits.
As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supply’s
rated voltage of 36V and rated output current of 1.2A, 1.5A, and each driver is pin-compatible so that replacement can be
done easily. Also it makes μ-STEP drive possible by inputting external DAC signal so that it provides wider application
area. There are excitation modes of FULL STEP & HALF STEP mode. This series contributes to reduction of mounting
area, cost down, safety design.
●Feature
1) Power supply: one system drive (rated voltage of 36V)
2) Rated output current: 1.2A, 1.5A
3) Low ON resistance DMOS output
4) Parallel IN drive mode
5) 2ch drive DC motor
6) PWM constant current control (self oscillation)
7) Built-in spike noise cancel function (external noise filter is unnecessary)
8) FULL STEP applicable to HALF STEP
9) Applicable to μstep drive
10) Forward/reverse break mode for DC motor
11) Power save function
12) Built-in logic input pull-down resistor
13) Power-on reset function
14) Thermal shutdown circuit (TSD)
15) Over current protection circuit (OCP)
16) Under voltage lock out circuit (UVLO)
17) Over voltage lock out circuit (OVLO)
18) Malfunction prevention at the time of no applied power supply (Ghost Supply Prevention)
19) Electrostatic discharge: 4kV (HBM specification)
20) Microminiature, ultra-thin and high heat-radiation (exposed metal type) HTSSOP package
21) Pin-compatible line-up
●Application
Laser beam printer, Scanner, Photo printer, FAX, Ink jet printer, Mini printer, Sewing machine, Toy, and Robot etc.
