The CS8442 is a stepper motor
driver that implements an H-
bridge design to drive two coils in
an eight step sequence each revo-
lution. Each H-bridge is capable of
delivering 85mA to the load.
The sequencer function insures
that the odometer is monotonic
and that cross-conduction of each
H bridges does not occur. Before
the beginning of each sequence,
both bridges are turned off. This
òdead zoneó minimizes the fly
back energy generated in the
inductive loads. In addition, on
board clamp diodes across each
output protect the output drive
transistors from excessive fly back
voltages.
The CS8442 is fault protected
against reverse battery, short cir-
cuit, and over voltage conditions.
If a fault is detected, the IC shuts
down.
The buffered speed signal output
(SENSOR OUT) is an open collec-
tor NPN capable of driving a
4.7k load connected to a 5V sup-
ply. The signal is a buffered,
inverted version of the speed sen-
sor input voltage (SENSOR IN).
The input voltage can be either a
sine or square wave form.
