Description and Introduction

Two-Phase Unipolar Driver for Variable-Speed Fan Motor The LB1965 is a motor driver IC manufactured by ON Semiconductor. Here are its specifications, descriptions, and features:

### **Specifications:**
- **Type:** Brushless DC (BLDC) Motor Driver  
- **Operating Voltage Range:** 4.5V to 16V  
- **Output Current:** Up to 1.5A (continuous)  
- **Number of Outputs:** 3 (for 3-phase motor control)  
- **Control Interface:** PWM input for speed control  
- **Protection Features:** Overcurrent protection, thermal shutdown, and undervoltage lockout (UVLO)  
- **Package Type:** HSOP-8 (Exposed Pad)  

### **Descriptions:**
The LB1965 is a compact, high-efficiency motor driver IC designed for driving small brushless DC motors. It integrates three half-bridge outputs with built-in protection features, making it suitable for applications like cooling fans, small pumps, and other low-power motor systems.  

### **Features:**
- **3-Phase Full-Wave Drive:** Enables smooth and efficient motor operation.  
- **Built-in PWM Control:** Allows speed regulation via an external PWM signal.  
- **Low On-Resistance MOSFETs:** Enhances efficiency and reduces heat generation.  
- **FG (Frequency Generator) Output:** Provides motor speed feedback.  
- **Standby Function:** Reduces power consumption when not in use.  
- **Compact Package:** HSOP-8 with an exposed pad for improved thermal dissipation.
