Description and Introduction

PWM Current Control Type DC Motor Driver The LB1947 is a motor driver IC manufactured by SANYO. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Bipolar Stepper Motor Driver IC  
- **Output Current:** 1.0 A (max)  
- **Supply Voltage (VCC):** 4.5 V to 16 V  
- **Logic Supply Voltage (VDD):** 4.5 V to 5.5 V  
- **Number of Outputs:** 4 (for bipolar stepper motor control)  
- **Package:** HSOP20 (Heat Sink Small Outline Package)  
- **Operating Temperature Range:** -20°C to +75°C  

### **Descriptions:**  
- The LB1947 is designed for driving bipolar stepper motors in applications such as printers, office automation equipment, and industrial machines.  
- It integrates control logic, power MOSFETs, and protection circuits in a single package.  
- Supports full-step and half-step driving modes.  

### **Features:**  
- **Built-in PWM Current Control:** Reduces power dissipation.  
- **Low ON-Resistance Output MOSFETs:** Improves efficiency.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Under-Voltage Lockout (UVLO):** Ensures safe operation during low voltage conditions.  
- **Internal Clamp Diodes:** Protects against back EMF from the motor.  

For detailed electrical characteristics and application circuits, refer to the official SANYO datasheet for the LB1947.
