Stepping Motor Drivers

BD6422EFV (PARALLEL-IN type)

BD6425, BD6423EFV (CLK-IN type)

No.12009EAT06

●Description

These products are a low power consumption PWM constant current-drive driver of bipolar stepping motor with power

supply’s rated voltage of 45V and rated output current of 1.0A, 1.5A.

●Feature

1) Power supply: one system drive (rated voltage of 45V)

2) Rated output current: 1.0A, 1.5A

3) Low ON resistance DMOS output

4) CLK-IN drive mode (BD6425/6423EFV)

5) Parallel IN drive mode (BD6422EFV)

6) PWM constant current control (other oscillation)

7) Built-in spike noise blanking function (external noise filter is unnecessary)

8) FULL STEP & HALF STEP (two kinds), applicable to QUARTER STEP

9) Current decay mode switching function (4 kinds of FAST/SLOW DECAY ratio)

10) Normal rotation & reverse rotation switching function (BD6425/6423EFV)

11) Power save function

12) Built-in logic input pull-down resistor

13) Power-on reset function(BD6425/6423EFV)

14) Thermal shutdown circuit (TSD)

15) Over current protection circuit (OCP)

16) Under voltage lock out circuit (UVLO)

17) Malfunction prevention at the time of no applied power supply (Ghost Supply Prevention)

18) Electrostatic discharge: 8kV (HBM specification)

19) Microminiature, ultra-thin and high heat-radiation (exposed metal type) HTSSOP package

●Application

serial dot impact printer､sewing machine etc.

●Absolute maximum ratings(Ta=25℃)
