General Description

The MBC05641 Microstep Motor Driver has an output current capability of 0.5 Amps minimum to 5.0

Amps maximum (Peak Rating). The MBC05641 driver operates from a DC voltage of 24-48 Volts. The

inputs are optically isolated with a minimum sourcing of 7.0mA per input (+3.5VDC minimum to +24VDC

maximum). The clock input is set to receive either positive or negative edge clocks with a maximum fre-

quency of 400kHz. The MBC05641 driver offers direction control and motor current ON/OFF capabilities.

The Reduce Current Enabled automatically reduces motor current to 50% of set value after the last step

is made (1sec delay). The driver has built-in features to indicate power on (Green LED), clocks being

received (Yellow LED), and fault conditions (Red LED).

With the MBC05641, various step resolutions can be implemented by the onboard dip switch. These divi-

sions range from 200 steps per revolution to 12,800 steps per revolution. The bipolar drive conﬁ guration

handles 4, 6 and 8 lead motors. Protection devices have been added to this driver for Phase to Phase

Short-Circuit conditions.

Pin Descriptions

The inputs on the MBC05641 are optically isolated with the anode (+) and cathode (-) both brought out

to the user. With no current going through the opto-diode the input is considered high. To enable the

input a minimum of 7.0mA needs to be sourced or sinked through the opto-diode. This is done simply by

placing a voltage of +3.5 to +24VDC across the two inputs of the opto-diode. If sourcing current into the

inputs, then all three cathodes (-) should be tied together and grounded as shown in Figure 2. If sinking

current, then all three anodes (+) should be tied together to the +voltage as shown in Figure 1. Provided

on the MBC05641 is an external +5VDC out which can be used to power the inputs for sinking mode only.

However, if you use this +5 voltage, isolation is not preserved.
