Description and Introduction

PUSH-PULL FOUR CHANNEL DRIVERS The L293B is a quadruple half-H driver manufactured by STMicroelectronics (STM). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Current:** 1A per channel (peak current up to 2A)  
- **Supply Voltage (VCC):** 4.5V to 36V  
- **Logic Supply Voltage (VSS):** 4.5V to 7V  
- **Operating Temperature Range:** -40°C to +150°C  
- **Output Clamp Diodes:** Included for inductive load protection  
- **Package:** PowerDIP16, SO-16  

### **Descriptions:**  
- The L293B is designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors.  
- It consists of four independent half-H bridge drivers, allowing bidirectional control of two DC motors or one stepper motor.  
- The device includes built-in diodes to suppress voltage spikes from inductive loads.  

### **Features:**  
- **Four Half-H Drivers:** Enables control of two DC motors or one stepper motor.  
- **Wide Supply Voltage Range (4.5V–36V):** Suitable for various motor types.  
- **Thermal Shutdown:** Protects the IC from overheating.  
- **High-Noise Immunity Inputs:** Ensures stable operation in noisy environments.  
- **Separate Logic and Motor Supply:** Allows flexible voltage levels for control and power stages.  

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