www.DataSheet4U.com CS8441 Stepper Motor Driver with Divide by Select The CS8441 is a Stepper Motor Driver that implements an H–Bridge design in order to drive two coils in an eight step sequence per revolution in the divide by 1 mode; 16 step sequence in the divide by 2 mode. The H–Bridge is capable of delivering 85 mA to the load. The sequencer insures that the odometer is monotonic. This sequencer is configured such that simultaneous conduction does not occur. Before each successive output sequence the part is taken through a state where both outputs are turned off individually. This tends to minimize the inductive kick back energy that the part must absorb. On–chip clamp diodes are across each output to protect the part from the kick back energy that it must absorb.
