2 General Description The BLD72 is a step motor driver that can drive motors rated from 1 to 7 amps/phase (unipolar rating). It can handle 6 lead and 8 lead motors. This driver features a unipolar bilevel (or dual voltage) drive tech- nique with short and open circuit protection (with a Fault LED).
3 Clock Modes The BLD72 has two clock options: Clock and Direction, or Dual Clock operation. Jumper JP2 is used to select the clock option. Basically JP2 selects Terminal 5 as either the Direction input or the CCW input.
4 Fault Protection There are 3 types of fault detection. When a fault is detected, the driver turns off the motor current and the red Fault LED indicates which type of fault occurred.
