APPLICATION INFORMATION
General
The MC3479 integrated circuit is designed to drive a
stepper positioning motor in applications such as disk drives
and robotics. The outputs can provide up to 350 mA to each
of two coils of a two−phase motor. The outputs change state
with each low−to−high transition of the clock input, with the
new output state depending on the previous state, as well as
the input conditions at the logic controls.
Outputs
The outputs (L1−L4) are high current outputs (see
Figure 5), which when connected to a two−phase motor,
provide two full−bridge configurations (L3 and L4 are not
shown in Figure 5). The polarities applied to the motor coils
depend on which transistor (QH or QL) of each output is on,
which in turn depends on the inputs and the decoding
circuitry.
Note: tr, tf (10% to 90%) for
input signals are
p 10 ns.

The maximum sink current available at the outputs is a
function of the resistor connected between Pin 6 and ground
(see section on Bias/Set operation). Whenever the outputs
are to be in a high impedance state, both transistors (QH and
QL of Figure 5) of each output are off.
