Description and Introduction

Standalone 750mA Li-Ion Battery Charger in 2 x 2 DFN with NTC Thermistor Input The LTC4069EDC#PBF is a battery charger IC manufactured by **Linear Technology** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Linear Technology (Analog Devices)  
- **Part Number:** LTC4069EDC#PBF  
- **Package:** DFN-6 (2mm x 2mm)  
- **Input Voltage Range:** 4V to 10V  
- **Charge Voltage:** 4.2V (adjustable)  
- **Charge Current:** Up to 750mA (programmable)  
- **Charge Termination:** C/10 or timer-based  
- **Operating Temperature Range:** -40°C to +85°C  
- **Battery Chemistry:** Single-cell Li-Ion/Polymer  

### **Descriptions:**
- A standalone linear battery charger designed for single-cell Li-Ion/Polymer batteries.  
- Features an integrated pass transistor and reverse-blocking diode, eliminating the need for external components.  
- Includes thermal regulation to prevent overheating during high-power charging.  

### **Features:**
- **Programmable Charge Current:** Adjustable via an external resistor.  
- **Automatic Recharge:** Initiates charging if battery voltage falls below a threshold.  
- **Charge Status Output:** Provides indication of charging, termination, and fault conditions.  
- **Thermal Regulation:** Reduces charge current if die temperature exceeds a safe limit.  
- **No External MOSFET or Diode Required:** Integrated power components simplify design.  
- **Low Battery Leakage Current:** <1µA when input power is removed.  

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