SLA7044M

MICROSTEPPING, UNIPOLAR PWM,

HIGH-CURRENT MOTOR CONTROLLER/DRIVER

The SLA7042M and SLA7044M are designed for high-efficiency

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

stepper motors. Microstepping provides improved resolution without

limiting step rates, and provides much smoother low-speed motor

operation. An automated, innovative packaging technology combined

with power NMOS FETs and monolithic CMOS logic/control circuitry

advances power multi-chip modules (PMCMs™) toward the complete

ler/drivers operate independently. The 4-bit shift registers are serially

loaded with motor phase information and output current-ratio data (eight

levels). The combination of user-selectable current-sensing resistor,

linearly adjustable reference voltage, and digitally selected output

current ratio provides users with a broad, variable range of of full, half,

and microstepping motor control (I_OUT≈ [V_REF/3 • R_S] • Current Ratio).

Each PMCM is rated for a maximum motor supply voltage of 46 V

and utilizes 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. Highly
