SLA7050M  
PRELIMINARYINFORMATION  
(subject to change without notice)  
February 19, 2003  
UNIPOLAR STEPPER-MOTOR  
TRANSLATOR/PWM DRIVER  
Combining low-power CMOS logic with high-current, high-voltage  
power FET outputs, the SLA7050M 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 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 torque-  
speed 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.  
The SLA7050M is supplied in an 18-pin single in-line power-tab  
package with leads formed for vertical mounting (suffix LF871) or  
horizontal mounting (suffix LF872). The tab is at ground potential and  
needs no insulation. For high-current or high-frequency applications,  
external heat sinking may be required. This device is rated for continu-  
ous operation between -20°C and +85°C.

* Output current rating may be limited by duty cycle,  
ambient temperature, and heat sinking. Under any set of  
conditions, do not exceed the specified current rating or  
junction temperature.  
† Internal filtering provides protection against transients  
during the first 1 µs of the current-sense pulse.
