The MBC158 Microstepping Motor Driver contains our latest driver technology. It has an output current capability of from 0.25 Amps Minimum to 1.5 Amps Maximum (1.5 Amps continuous). The driver will operate off 12V DC Minimum to 48V DC Maximum. The inputs are Opto lsolated with a minimum sourcing of 5 mA per input (5V DC Minimum to 12V DC 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 (20 msec delay). The +5V DC output supply is dependent on the input DC Supply Voltage (200mA @ 48V DC, 450mA @ 24V DC and 1000mA @ 12V). The driver has built-on features to indicate power on (Green LED) and Clocks being received, greater than 100 Hz (Yellow LED).
