Ideal pentru CNC sau 3D printer

GENERAL DESCRIPTION:
The NJM3771 & NJM3772 is a stepper motor driver, which circuit is
especially developed for use in microstepping applications
in conjunction with the matching dual DAC (Digital-to-
-Analog Converter) NJU39610.
The NJM3771 & NJM3772 contains a clock oscillator, which is
common for both driver channels; a set of comparators and
flip-flops imple menting the switching control; and two
H-bridges with internal recirculation diodes. Voltage supply
requirements are +5 V for logic and +10 to +45 V for the
motor. Maximum output current is 650 mA per channel for NJM3771 and 1000mA per channel for NJM3772

Circuitul necesita foarte putine componente externe. (10buc)

Pretul cuprinde o pereche de ICs pentru un motorul pas cu pas
(NJM3771 SAU NJM3772) si NJU39610
