Description and Introduction

Dual BTL power driver The TDA7073AT is a motor driver IC manufactured by THI (Thomson Semiconductors). Below are the specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Supply Voltage (VCC):** 5.5V to 18V  
- **Output Current:** Up to 1.2A (per channel)  
- **Number of Channels:** Dual (2-channel)  
- **Package:** SO20 (20-pin Small Outline package)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Control Input Voltage:** Compatible with TTL/CMOS levels  

### **Descriptions:**  
- The TDA7073AT is a dual BTL (Bridge-Tied Load) motor driver IC designed for DC motor control applications.  
- It features built-in protection against short circuits, thermal shutdown, and undervoltage lockout.  
- The device is suitable for driving small DC motors in consumer electronics, automotive systems, and industrial applications.  

### **Features:**  
- **Dual BTL Outputs:** Allows independent control of two DC motors.  
- **PWM Control:** Supports pulse-width modulation for speed regulation.  
- **Low Standby Current:** Reduces power consumption when idle.  
- **Thermal Protection:** Shuts down the device in case of overheating.  
- **Short-Circuit Protection:** Safeguards against output shorts.  
- **Wide Supply Voltage Range:** Supports operation from 5.5V to 18V.  

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

Application Scenarios & Design Considerations

Dual BTL power driver

Alternative Part Number

  • L272M --: Dual power operational amplifier in a DIP-8 package, commonly used as a drop-in replacement for the TDA7073A in motor and actuator driver circuits.
  • LM358N --: Widely available dual op-amp in DIP-8 with similar supply range and pinout, suitable for low-power driver applications where the TDA7073AT is used.
  • TCA0372DP1 --: Dual power op-amp rated for higher output current, pin-compatible with many TDA7073A sockets and well suited for motor drive and servo applications.
  • TDA7073A --: Same dual BTL power driver family without the package/ordering suffix; functionally equivalent and widely available.
  • TDA8560Q --: Similar dual BTL audio power driver in the same TDA series, suitable as a functional substitute with comparable output capability.
  • LM4950TA --: Dual bridge-tied-load audio power amplifier offering comparable drive capability as a cross-manufacturer alternative.
  • L293D --: General-purpose dual H-bridge driver that can replace the TDA7073AT in many low-voltage bidirectional drive designs with minor circuit adaptation.
  • LM675T --: High-current power operational amplifier in a TO-220 package that can replace the TDA7073A in single-channel driver circuits where higher output current is needed.
  • SN754410 --: Quad half-H driver with similar voltage and current ratings, pin-compatible with L293-style drivers and suitable for bidirectional DC motor drive applications.
  • TDA1552Q --: Comparable dual BTL power amplifier/driver IC suitable as a functional replacement after verifying pin compatibility.
