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 85mA 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.
Additional part protection is provided by two functions. The first being "short circuit protection". This function will protect the part in the case of a shorted or partially shorted load. The second protection function is the "overvoltage function". This function monitors the level of the supply voltage. In transient conditions such as load dump, the part will shut down, protecting itself.
