Description and Introduction

4A, High Efficiency, Li-Ion Battery Charger The LTC4007EUFD-1 is a battery charger controller manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 38V  
- **Battery Voltage Range:** 1V to 38V  
- **Charge Current:** Programmable up to 10A  
- **Charge Termination:** C/10 or Timer-Based  
- **Charge Accuracy:** ±0.5%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 28-Lead QFN (5mm × 5mm)  

### **Descriptions:**
- The LTC4007EUFD-1 is a high-efficiency synchronous buck battery charger controller designed for single-cell to multi-cell Li-Ion/Polymer, LiFePO4, or lead-acid batteries.  
- It supports constant-current/constant-voltage (CC/CV) charging with programmable charge current and voltage.  
- The device includes input current limiting, reverse battery protection, and thermal regulation.  

### **Features:**
- **Wide Input & Battery Voltage Range:** Supports 4.5V–38V input and 1V–38V battery.  
- **High Efficiency:** Synchronous rectification minimizes power loss.  
- **Programmable Charge Parameters:** Adjustable charge current, voltage, and termination.  
- **Input Current Limiting:** Prevents overloading the input supply.  
- **Reverse Battery Protection:** Safely handles reverse battery connections.  
- **Thermal Regulation:** Reduces charge current if overheating occurs.  
- **Status Indicators:** Provides charge status via open-drain outputs.  
- **Small Footprint:** 28-Lead QFN package for space-constrained applications.  

For detailed application information, refer to the official datasheet from Analog Devices.
