Description and Introduction

4A, High Efficiency, Multi-Chemistry Battery Charger The **LTC4008EGN#PBF** is a battery charger controller manufactured by **Linear Technology** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Linear Technology (Analog Devices)  
- **Part Number:** LTC4008EGN#PBF  
- **Type:** Standalone Li-Ion/Polymer Battery Charger Controller  
- **Input Voltage Range:** 4.5V to 32V  
- **Charge Voltage Range:** 4.0V to 28V (adjustable)  
- **Charge Current:** Programmable up to 4A  
- **Battery Chemistry Support:** Li-Ion, Li-Polymer, LiFePO4  
- **Charge Termination:** C/10 or Timer-Based  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP  

### **Descriptions:**
- The LTC4008EGN#PBF is a high-efficiency switching battery charger controller designed for single or multi-cell Li-Ion/Polymer batteries.  
- It includes an internal synchronous PWM controller for high-efficiency power conversion.  
- Features automatic power path management, allowing the system to operate from the input supply even when the battery is deeply discharged.  
- Supports both constant-current (CC) and constant-voltage (CV) charging modes.  

### **Features:**
- **Wide Input Voltage Range:** 4.5V to 32V, suitable for various power sources.  
- **Programmable Charge Current:** Up to 4A with external sense resistor.  
- **Automatic Recharge:** Initiates charging if battery voltage falls below a threshold.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds a safe limit.  
- **Battery Detection:** Ensures no charging occurs if the battery is absent or faulty.  
- **Power Path Management:** Seamlessly powers the system while charging the battery.  
- **Status Indicators:** Provides charge status via open-drain outputs.  
- **Low Battery Quiescent Current:** Minimizes power loss when not charging.  

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