UNIPOLAR STEPPER-MOTOR TRANSLATOR/PWM DRIVER

Combining low-power CMOS Logic with high-current, High-Voltage power FET outputs, the SLA7051M 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 (PMCMT).
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 2 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.
