DESCRIPTION
The MBC158 Microstep Motor Driver has an output current capability from \
0.2 Amps Mini-
mum to 1.5 Amps Maximum (Peak Rating).  The MBC158 driver will operate off 12VDC Min-
imum to 48VDC Maximum (up to 1.75 Amps).  The inputs are Opto-Isolated with a minimum 
sourcing of 5 mA per input (5VDC Minimum to 12VDC Maximum).  The clock input is set to 
receive negative edge clocks with a maximum frequency of 100k Hz.  The direction input is 
current sourcing for CW and no current for CCW.  The ON/OFF feature is current sourcing to 
de-energize the step motor and no current to energize the motor.  Reduce Current Enabled 
automatically reduces Motor current 50% after last step (20msec delay)\
.  The +5VDC output 
supply is dependent on the input DC Supply Voltage (200mA @ 48VDC, 450mA @ 24VDC 
and 1000mA @ 12VDC).  The driver has built-on features to indicate power on (Green LED) 
and built-on features to indicate power on (Green LED) and Clocks bein\
g received, greater 
than 100Hz (Yellow LED).

SPECIFICATIONS
PinName Description
1 Opto Supply 5VDC Minimum to 12VDC Maximum @ 50mA maximum is required to power the opto-isolated 
inputs (Clock, Direction and On/Off).
2 Direction The DIRECTION input controls the direction in which the motor steps.  If\
 the DIRECTION 
input is high the motor will step in the counterclockwise (CCW) direct\
ion.
3 Clock The Clock input is the stepping clock for the driver.  When the clock input transitions from high 
to low, the motor takes one step.
4 On/Off The ON/OFF input controls the motor.  If the ON/OFF input is high, the motor will step with the 
clock and will have holding current at standstill.  If the ON/OFF input \
is low the motor will be 
turned off with no holding current and clock signals will be ignored.  When the O\
N/OFF input 
becomes high again, the motor will hold at the step it was in when the O\
N/OFF input went low.
5 5VOUT The 5VOUT pin provides a regulated 5VDC output from the driver.  The +5VDC output sup
-
ply is dependent on the input DC Supply Voltage (200mA @ 48VDC, 450mA @ 24VDC and 
1000mA @ 12VDC).
6 +VIN Input power supply requirement is 12VDC minimum to 48VDC maximum.
7 0VDC This pin is the return/reference point for +VIN and +5VOUT.
The logic inputs to the MBC158 are of the sourcing type, meaning that an\
 input left open 
will automatically be pulled up to a high level.  To drive an input low, tie it to ground di-
rectly or use a saturated transistor.
