Description and Introduction

ALTERNATOR VOLTAGE REGULATOR The MC33092DW is a stepper motor controller manufactured by Motorola (now part of ON Semiconductor).  

### **Specifications:**  
- **Package:** SOIC-28 (DW suffix)  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Output Current (Peak):** Up to 750mA per winding  
- **Control Method:** Microstepping (full-step, half-step, quarter-step)  
- **Logic Input Compatibility:** TTL/CMOS  
- **Operating Temperature Range:** -40°C to +85°C  
- **Protection Features:** Thermal shutdown, under-voltage lockout  

### **Descriptions:**  
The MC33092DW is a monolithic IC designed for bipolar stepper motor control. It integrates a translator, PWM current control, and power drivers, simplifying motor control system design. It supports microstepping for smoother motion and reduced vibration.  

### **Features:**  
- Built-in translator for step and direction inputs  
- Adjustable current control via external sense resistors  
- PWM chopper drive for constant current regulation  
- Selectable step modes (full, half, quarter-step)  
- Low-power sleep mode  
- Fault detection and protection  

This information is based on Motorola's documentation. For detailed specifications, refer to the official datasheet.

Application Scenarios & Design Considerations

ALTERNATOR VOLTAGE REGULATOR

Alternative Part Number

  • SG3524N --: Classic PWM controller IC in a DIP package with similar regulation and oscillator functions, widely available and well documented as a general-purpose substitute.
  • TL494CN --: Industry-standard PWM control IC offering dual outputs and voltage regulation, commonly used where MC33092-class controllers are applied.
  • UC3842AN --: Current-mode PWM controller in DIP-8 with comparable control-loop behavior, suitable for many power-supply designs that used the MC33092.
