Description and Introduction

TOSHIBA Bi-CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC The part **TB31202** is a **2-channel H-bridge motor driver IC** manufactured by **Toshiba**. Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage (VCC):** 4.5V to 16V  
- **Output Current (Continuous per Channel):** 1.0A (Max)  
- **Output Current (Peak per Channel):** 2.0A (Max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** **HSOP8-P-300-1.00** (8-pin surface-mount package)  
- **Logic Input Voltage (VIN):** 3.3V or 5V compatible  

### **Descriptions:**  
- Designed for driving **DC motors, stepper motors, and other inductive loads**.  
- Includes **built-in protection features** such as thermal shutdown and under-voltage lockout (UVLO).  
- Supports **PWM (Pulse-Width Modulation) control** for speed regulation.  

### **Features:**  
- **Low ON-Resistance:** Reduces power loss.  
- **Standby Function:** Low current consumption when disabled.  
- **Independent Channel Control:** Each H-bridge can be controlled separately.  
- **Wide Operating Voltage Range:** Suitable for various battery-powered applications.  
- **Compact Package:** Space-saving design for PCB integration.  

This IC is commonly used in **robotics, automotive systems, and consumer electronics** requiring precise motor control.
