Description and Introduction

Isolated Feedback Generator The UC3901 is a battery charger controller manufactured by Texas Instruments (formerly Unitrode Corporation, UCC).  

### **Specifications:**  
- **Input Voltage Range:** Up to 40V  
- **Output Voltage Range:** Adjustable  
- **Charge Modes:** Supports trickle, constant-current, and constant-voltage charging  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** PDIP (Plastic Dual In-Line Package), SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
The UC3901 is a monolithic integrated circuit designed for lead-acid battery charging applications. It provides precise control over the charging process, ensuring optimal battery performance and longevity.  

### **Features:**  
- **Three-Stage Charging Control:** Automatically transitions between trickle, constant-current, and constant-voltage modes.  
- **Programmable Charge Current:** Allows adjustment of charging current based on battery requirements.  
- **Voltage Sensing:** Monitors battery voltage to prevent overcharging.  
- **Thermal Protection:** Includes built-in safeguards to prevent overheating.  
- **Low Standby Current:** Minimizes power consumption when not actively charging.
