Description
BD6387EFV, BD6385EFV, BD6383EFV, BD6389FM are the high-grade type that provides the highest function and highest
reliance in the ROHM stepping motor driver series. This series has the perfect various protection circuits and reduces IC’s
generation of heat by adopting low-ON resistance DMOS and high heat-radiation power package.
As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supplys rated
voltage of 36V and rated output current of 1.0A2.2A. For the input interface, the CLK-IN drive mode and the parallel IN
drive mode are compatible with each other, so please choose an input mode according to needs of application. There are
excitation modes of FULL STEP & HALF STEP (2 kinds), QUARTER STEP mode, and for current decay mode, the ratio of
FAST DECAY & SLOW DECAY can be freely set, so the optimum control conditions for every motor can be realized. In
addition, being able to drive with one system of power supply makes contribution to the set design’s getting easy.
Feature
1) Power supply: one system drive (rated voltage of 36V)
2) Rated output current: 1.0A, 1.5A, 2.0A, 2.2A
3) Low ON resistance DMOS output
4) CLK-IN drive mode (built-in translator circuit)
5) Parallel IN drive mode
6) Stepping motorDC motor(×2) drives are selectable
7) PWM constant current control (self oscillation)
8) Built-in spike noise cancel function (external noise filter is unnecessary)
9) FULL STEP & HALF STEP (two kinds), applicable to QUARTER STEP
10) Applicable to the μSTEP drive
11) Current decay mode switching function (linearly variable FAST/SLOW DECAY ratio)
12) Normal rotation & reverse rotation switching function
13) Power save function
14) Built-in logic input pull-down resistor
15) Power-on reset function
16) Thermal shutdown circuit (TSD)
17) Over current protection circuit (OCP)
18) Under voltage lock out circuit (UVLO)
19) Over voltage lock out circuit (OVLO)
20) Malfunction prevention at the time of no applied power supply (Ghost Supply Prevention)
21) Electrostatic discharge: 6kV (HBM specification)
22) Adjacent pins short protection
23) Inverted mounting protection
24) Microminiature, ultra-thin and high heat-radiation (exposed metal type) HTSSOP package
(BD6387EFV/BD6385EFV/BD6383EFV)
25) FIN heat-radiating type HSOP package (BD6389FM)
26) Pin-compatible line-up (BD6387EFV/BD6385EFV/BD6383EFV or BD6389FM)
Application
PPC, multi-function printer, laser beam printer, ink jet printer, monitoring camera, WEB camera, sewing machine, photo
printer, FAX, scanner, mini printer, toy, and robot etc.
