The SLA7026M is a high-current PWM, unipolar Stepper Motor Controller/Driver, designed for high-efficiency and high-performance operation of 2-phase. 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. It provides exceptionally reliable PMCMs suitable for controlling and directly driving a broad range of 2-phase, unipolar stepper motors. The avalanche-rated (100V) 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. In demanding, higher-current systems designs, necessitates suitable heat transfer methods for reliable operation.
