Description and Introduction

Brushless Motor Drivers (2-phase drive): 12 V/24 V fan motor driver The LB1867M is a motor driver IC manufactured by ROHM Semiconductor. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** ROHM Semiconductor  
- **Type:** Motor Driver IC  
- **Output Configuration:** Pre-driver  
- **Operating Voltage Range:** 4.5V to 16V  
- **Output Current:** Up to 1.5A (peak)  
- **Control Method:** PWM (Pulse Width Modulation)  
- **Package:** HSOP20 (20-pin)  
- **Built-in Protection Features:** Overcurrent protection (OCP), Thermal shutdown (TSD)  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions:**  
The LB1867M is a pre-driver IC designed for driving brushless DC motors (BLDC) or stepper motors. It integrates PWM control and protection circuits, making it suitable for applications requiring precise motor speed control.  

### **Features:**  
- **PWM Control:** Supports efficient motor speed regulation.  
- **Low ON-Resistance:** Reduces power loss in motor driving.  
- **Built-in Protection:** Includes overcurrent and thermal shutdown for enhanced reliability.  
- **Wide Operating Voltage:** Compatible with 4.5V to 16V systems.  
- **Compact Package:** HSOP20 for space-constrained applications.  

This information is based solely on the manufacturer's documentation. For detailed application notes or further specifications, refer to ROHM's official datasheet.
