The AA2920 is a CMOS integrated circuit based hybrid step motor driver ideally
suited for the design of 4-phase unipolar bilevel step motor drivers. This hybrid can
be used to design
half-step
and
full-step
bilevel type drivers.
The basic function of this hybrid is to take input (i.e. clock and direction) signals and
turn them into appropriate phase signals that are used to drive output transistors.
In most applications, the end user simply adds a few components along with power
transistors for the output stage. This results in low cost, compact, and reliable
designs.
The AA2920 comes in a 34-pin hybrid package. Dimensions below are in inches.
