www.DataSheet4U.com CS4161 85 mA Dual H-Bridge Odometer Driver with Divide by Select and UVLO The CS4161 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.
