Description and Introduction

Standalone Linear Li-Ion Battery Charger with Thermistor Input The LTC4061EDD-4.4#TRPBF is a lithium-ion battery charger IC manufactured by Linear Technology (now part of Analog Devices). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.35V to 6.5V  
- **Charge Voltage:** 4.4V (fixed)  
- **Charge Current:** Up to 1A (programmable)  
- **Termination Current:** 10% of programmed charge current  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  
- **Charging Method:** Constant-Current/Constant-Voltage (CC/CV)  

### **Descriptions:**
- Designed for single-cell lithium-ion/polymer batteries.  
- Integrated thermal regulation prevents overheating.  
- Automatic recharge when battery voltage falls below 4.2V.  
- No external MOSFET or blocking diode required.  
- Low dropout operation allows charging from weak power sources.  

### **Features:**
- **Programmable Charge Current:** Set via an external resistor.  
- **Thermal Regulation:** Reduces charge current if temperature rises.  
- **Automatic Power Path Management:** Powers system while charging.  
- **Battery Detection:** Ensures no battery is present before charging.  
- **Status Indicators:** Open-drain outputs for charging and fault conditions.  
- **Low Quiescent Current:** Minimizes power loss when not charging.  

This IC is suitable for portable applications requiring a compact, high-efficiency battery charging solution.
