2-Phase Unipolar Stepper Motor Driver

SLA707xM Series

February, 2006

■General Description

■Package—SLA23Pin

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

power FET outputs, the Series SLA707xM 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, 1.5, 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.

Full-,and Half-step operation are externally selectable for the

SLA7070/71/72/73MR. Full-, Half-, quarter-, and eighth-, and

sixteenth-step operation are externally selectable for the

SLA7075/76/77/78MR.

Half-step excitation alternates between the one-phase and two-phase

modes (A-AB-B-AB-A-AB-BAB),providing an eight-step sequence.
