The SLA4033 is a high-power stepper motor driver manufactured by Sanken Electric Co., Ltd.

Specifications:

  • Motor Type: Bipolar stepper motor
  • Output Current: Up to 3.5A (adjustable)
  • Supply Voltage (VM): 10V to 40V
  • Logic Voltage (VCC): 5V
  • Step Modes: Full-step, half-step, microstepping (depending on external control)
  • Protection Features: Overcurrent, thermal shutdown, undervoltage lockout
  • Package: Multiwatt15 (through-hole mounting)

Descriptions:

The SLA4033 is a unipolar/bipolar stepper motor driver IC designed for high-power applications. It integrates power MOSFETs and control circuitry to drive stepper motors efficiently. It is commonly used in CNC machines, industrial automation, and robotics.

Features:

  • High current capability (3.5A per phase)
  • Built-in protection circuits (thermal, overcurrent, undervoltage)
  • Wide operating voltage range (10V–40V)
  • Compatible with 5V logic controllers (TTL/CMOS inputs)
  • Low saturation voltage for reduced power dissipation
  • External resistor for current adjustment

This driver is typically controlled via step and direction signals from a microcontroller or motion controller.
