MBC100

MBC100 Modular Bipolar Chopper Driver Bipolar Chopper Driver with Selectable Output Current from 200mA to 1A Half-step and Full-step Operation Automatic Standstill Current Reduction Two User-selectable Standstill Current Reduction Options: 66% and 33% ON/OFF Input to Control Motor without Powering Down the Driver Unit Operates From a Single, 8VDC - 40VDC Supply Clock Indicator Allows Visual Confirmation that Step Signals are Being Received DB9 Connectors for Inputs and Outputs Operation at Step Clock Speeds up to 10kHz Flexible Package Allows for Horizontal and www.DataSheet4U.com Vertical Mounting The MBC100 is a low-cost bipolar chopper driver designed to drive four-phase step motors rated up to 1A. The MBC100 is compact and self-contained, requiring only an 8VDC - 40VDC power source and clock input to operate. The maximum motor current can be adjusted from 200mA to 1A, by adjusting a potentiometer on the unit; no external resistors are required to set the current level. The inputs to the driver are of the sinking type for easy interfacing with other equipment. An ON/OFF input is provided, which allows the motor to be turned off without powering down the driver. The Halfstep/Fullstep input selects half-step or full-step operation. A direction input is also provided. When the motor has been at standstill for 2 seconds, the driver will enter a reduced current mode. The user can select the standstill reduced current to be 100% (no reduction), 66%, or 33% o...
