85mA Dual H-Bridge Odometer Driver
with Divide by Select
Description
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 revolu-
tion in the divide by 1 mode; 16 step
sequence in the divide by 2 mode.
The H-Bridge is capable of deliver-
ing 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 out-
put sequence the part is taken
through a state where both outputs
are turned off individually. This
tends to minimize the inductive
itself.

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 pro-
vided by two functions. The first
being òshort circuit protectionó.
This function will protect the part in
the case of a shorted or partially
shorted load. The second protection
function is the òovervoltage func-
tionó. This function monitors the
level of the supply voltage. In tran-
sient conditions such as load dump,
the part will shut down, protecting
