Description and Introduction

Lead-Acid Linear Charge Management IC The UC3906N is a battery charger controller manufactured by Unitrode (now part of Texas Instruments). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Unitrode (U)  
- **Function:** Lead-Acid Battery Charger Controller  
- **Operating Voltage Range:** 6V to 40V  
- **Output Drive Current:** Up to 25mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Pin DIP (Dual In-Line Package)  

### **Descriptions:**
- The UC3906N is a monolithic integrated circuit designed for controlling the charging of lead-acid batteries.  
- It provides precise voltage and current regulation to optimize battery charging cycles.  
- The device includes features for three-stage charging: **bulk charge, taper charge, and float charge**, ensuring efficient battery maintenance.  
- It is commonly used in uninterruptible power supplies (UPS), automotive systems, and industrial battery chargers.  

### **Features:**
- **Three-Stage Charging Control:** Automatically transitions between bulk, taper, and float modes.  
- **Programmable Charge Parameters:** Adjustable voltage and current limits.  
- **Onboard Voltage Reference:** Provides stable reference for accurate charging.  
- **Current Limiting:** Protects the battery and charger circuitry.  
- **Temperature Compensation:** Adjusts charging voltage based on ambient temperature.  
- **Low Standby Current:** Reduces power consumption when inactive.  
- **Status Indicators:** Outputs for charge status monitoring.  

This information is based solely on the manufacturer's datasheet and technical documentation.
