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.
