Description and Introduction

4-UNIT 1.5A DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE The part M54532FP is a stepper motor driver IC manufactured by MIT (Mitsubishi Electric). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **MIT (Mitsubishi Electric)**  

### **Part Number:**  
- **M54532FP**  

### **Description:**  
- The M54532FP is a **bipolar stepper motor driver IC** designed for driving stepper motors in applications such as printers, office automation equipment, and industrial machinery.  

### **Key Features:**  
1. **Output Configuration:**  
   - Dual H-bridge driver for bipolar stepper motors.  
   - Capable of driving two phases of a stepper motor.  

2. **Supply Voltage Range:**  
   - **Logic Supply (VDD):** 4.5V to 5.5V  
   - **Motor Supply (VM):** Up to 36V  

3. **Output Current:**  
   - Maximum output current per phase: **750mA** (typical).  

4. **Control Inputs:**  
   - Compatible with TTL and CMOS logic levels.  
   - Includes **phase control inputs** for forward/reverse rotation.  

5. **Protection Features:**  
   - Built-in **thermal shutdown** protection.  
   - **Overcurrent protection** to prevent damage to the IC.  

6. **Package Type:**  
   - **FP (Plastic QFP - Quad Flat Package)**  
   - **Pin Count:** 24 pins.  

7. **Applications:**  
   - Printers (dot matrix, inkjet)  
   - Office automation equipment (scanners, copiers)  
   - Industrial automation (CNC machines, robotics)  

### **Additional Notes:**  
- The M54532FP is designed for **unipolar or bipolar stepper motor control** depending on the external circuit configuration.  
- It includes **internal clamping diodes** for inductive load protection.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

4-UNIT 1.5A DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE

Alternative Part Number

  • ULN2803A --: Eight-channel Darlington sink driver in a DIP/SOIC package, functionally equivalent to the M54532FP octal driver array and widely available.
  • ULN2803ADW --: SOIC-18 wide-body version of the ULN2803, matching the surface-mount footprint and drive capability of the M54532FP.
  • MC1413BDG --: Seven-channel high-voltage Darlington array with similar sink current and input characteristics, suitable as a drop-in functional replacement.
  • ULN2803AFWG --: Eight-channel Darlington sink driver in an SOP package, functionally equivalent to the M54532FP with similar output current and voltage ratings.
  • MC1413BDR2G --: Seven-channel Darlington transistor array in SOIC, electrically similar and often used as a substitute for Mitsubishi M54532FP drivers.
  • TD62083AP --: Eight-channel Darlington transistor array in a DIP package with comparable current rating and integrated clamp diodes, directly usable in similar relay/LED driving applications.
