2-Phase Unipolar Stepper Motor Driver  
SLA7050M/7051M/7052M  
October 2005  
■General Description  
■Package----SLA18Pin  
Combining low-power CMOS logic with high-current, high-voltage  
power FET outputs, the Series SLA705xM translator/driver provides  
complete control and drive for a two-phase unipolar stepper motor  
with internal fixed off time, pulse-width modulation (PWM) control  
of the output current in a power multi-chip module (PMCM™).  
The CMOS logic section provides the sequencing logic, direction,  
full/half-step control, synchronous/asynchronous PWM operation,  
and a "sleep" function. The minimum CLOCK input is an ideal fit  
for applications where a complex µP is unavailable or overburdened.  
TTL or LSTTL may require the use of appropriate pull-up resistors  
to ensure a proper input-logic high. For PWM current control, the  
maximum output current is determined by the user's selection of a  
reference voltage and sensing resistor. The NMOS outputs are  
capable of sinking up to 1,2 or 3 A and withstanding 46 V in the off  
state. Ground-clamp and flyback diodes provide protection against  
inductive transients. Special power-up sequencing is not required.  
Full-step (2 phase) and half-step operation are externally selectable.  
Two-phase drive energizes two adjacent phases in each detent  
position (AB-BC-CD-DA). This sequence mode offers an improved  
torquespeed product, greater detent torque, and is less susceptable to  
motor resonance. Half-step excitation alternates between the  
one-phase and two-phase modes (A-AB-B-BC-C-CD D-DA),  
providing an eight-step sequence.
