Description and Introduction

POWER AMPLIFIER FOR DRIVING A DEFLECTION CIRCUIT OF A COLOR TELEVISION The TA8432K is a motor driver IC manufactured by Toshiba. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** Toshiba  

### **Description:**  
The TA8432K is a PWM-controlled bipolar stepping motor driver IC. It is designed to drive two-phase bipolar stepping motors efficiently with built-in protection features.  

### **Key Features:**  
- **Output Current:** Up to 1.5A (peak) per phase  
- **Operating Voltage Range:** 10V to 40V  
- **PWM Current Control:** Adjustable via external resistors  
- **Built-in Protection Circuits:**  
  - Thermal shutdown  
  - Overcurrent protection  
  - Undervoltage lockout (UVLO)  
- **Control Modes:** Full-step, half-step, and microstep operation  
- **Low ON Resistance:** Reduces power dissipation  
- **Package:** SIP (Single In-line Package)  

### **Applications:**  
- Stepper motor control in printers, scanners, robotics, and industrial automation.  

This information is based on Toshiba's official documentation for the TA8432K.

Application Scenarios & Design Considerations

POWER AMPLIFIER FOR DRIVING A DEFLECTION CIRCUIT OF A COLOR TELEVISION

Alternative Part Number

  • L298N --: Dual H-bridge motor driver in a Multiwatt package, functionally similar to the TA8432K for driving DC and stepper motors, widely available and well documented.
  • L293D --: Quad half-H driver commonly used as a drop-in functional substitute for small motor drive applications, lower current rating but pin-compatible logic interface.
  • SN754410 --: Quadruple half-H driver with similar logic-level inputs and output structure, suitable replacement when lower drive current is acceptable.
