The SLA7024M, SLA7026M, and SMA7029M are designed for

high-efficiency and high-performance operation of 2-phase, unipolar

stepper motors.  An automated, innovative packaging technology

combined with power FETs and monolithic logic/control circuitry advances power multi-chip modules (PMCMs™) toward the complete

integration of motion control.  Highly automated manufacturing techniques provide low-cost and exceptionally reliable PMCMs suitable for

controlling and directly driving a broad range of 2-phase, unipolar

stepper motors.  The three stepper motor multi-chip modules differ

primarily in output current ratings (1.5 A or 3.0 A) and package style.

All three PMCMs are rated for an absolute maximum limit of 46 V

and utilize advanced NMOS FETs for the high-current, high-voltage

driver outputs.  The avalanche-rated (≥100 V) FETs provide excellent

ON resistance, improved body diodes, and very-fast switching.  The

multi-chip ratings and performance afford significant benefits and

advantages for stepper drives when compared to the higher dissipation

and slower switching speeds associated with bipolar transistors.

Normally, heat sinks are not required for the SLA7024M or SMA7029M.

The SLA7026M, in demanding, higher-current systems designs,

necessitates suitable heat transfer methods for reliable operation.

Complete applications information is given on the following pages.

PWM current is regulated by appropriately choosing current-sensing

resistors, a voltage reference, a voltage divider, and RC timing networks.  The RC components limit the OFF interval and control current

decay.  Inputs are compatible with 5 V logic and microprocessors.
