General Description
　　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 ?P 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.
