PRELIMINARYINFORMATION

(subject to change without notice)

August 19, 2003

SLA7060M THRU

SLA7067M

UNIPOLAR STEPPER-MOTOR

TRANSLATOR/DRIVERS

Combining low-power CMOS logic with high-current, high-voltage

power FET outputs, the Series SLA7060M translator/drivers provide

complete control and drive for a two-phase unipolar stepper motor with

internal fixed off time and pulse-width modulation (PWM) control of

the output current in a power multi-chip module (PMCM™). There are

no phase-sequence tables, high-frequency control lines, or complex

interfaces to program.

The CMOS logic section provides the sequencing logic, direction,

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 (depending on device) and withstanding 46 V in the off state.

Clamp diodes provide protection against inductive transients. Special

power-up sequencing is not required.

Half-, quarter-, eighth-, and sixteenth-step operation are externally

selectable for the SLA7060/61/62M. Full-step (2 phase), half-,

quarter-, and eighth-step operation are externally selectable for the

SLA7065/66/67M. Two-phase drive energizes two adjacent phases in

each detent position (AB-AB-AB-AB). This sequence mode offers an

improved torque-speed product, greater detent torque, and is less

susceptable to motor resonance. Half-step excitation alternates be-

tween the one-phase and two-phase modes (AB-B-AB-A-AB-B-AB-A),

providing an eight-step sequence.

The Series SLA7060M is supplied in a 21-pin single in-line power-

tab package with leads formed for vertical mounting (suffix LF2102).

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 continuous operation between -20°C and

+85°C.
