Description and Introduction

Dual Input USB/AC Adapter Standalone Li-Ion Battery Chargers The LTC4075EDD#PBF is a battery charger IC manufactured by Linear Technology (now part of Analog Devices). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 4V to 60V  
- **Charge Current:** Programmable up to 50mA  
- **Battery Float Voltage:** Adjustable (default 3.5V for Li-Ion/Li-Poly)  
- **Low Quiescent Current:** 1.5µA in standby mode  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead DFN (3mm × 3mm)  

### **Descriptions:**  
- Designed for **trickle charging** single-cell Li-Ion/Li-Polymer batteries or maintaining backup supercapacitors.  
- Features **low-power operation**, making it suitable for energy harvesting and long-life battery applications.  
- Includes **thermal regulation** to prevent overheating during high-power charging.  

### **Features:**  
- **Wide Input Voltage Range (4V–60V)** – Supports high-voltage inputs.  
- **Programmable Charge Current** – Adjustable via an external resistor.  
- **Automatic Recharge** – Initiates charging if battery voltage drops.  
- **Low Battery Drain** – Minimizes discharge when input power is removed.  
- **Thermal Regulation** – Reduces charge current if temperature rises.  
- **Small Footprint** – Compact DFN package for space-constrained designs.  

This IC is commonly used in **solar-powered systems, industrial backup power, and portable devices** requiring long battery life.  

(Note: Always refer to the official datasheet for detailed technical information.)
