●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 supply’s rated voltage of 36V and rated output current of 1.
0A～2.
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.
