LTC4065EDC LINEAR 48 In Stock

Description and Introduction

Standalone 750mA Li-Ion Battery Charger in 2 x 2 DFN The LTC4065EDC is a linear battery charger manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 6.5V  
- **Charge Current:** Up to 1A (programmable)  
- **Battery Chemistry:** Single-cell Lithium-Ion/Polymer  
- **Charge Termination:** C/10 or timer-based  
- **Preconditioning:** For deeply discharged batteries  
- **Charge Voltage Accuracy:** ±0.6%  
- **Thermal Regulation:** Prevents overheating  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 6-Lead DFN (2mm × 2mm)  

### **Descriptions and Features:**  
- **Linear Charger:** Uses a linear pass element for charging.  
- **Programmable Charge Current:** Adjustable via external resistor.  
- **Automatic Recharge:** Initiates charging when battery voltage falls below a threshold.  
- **Battery Detection:** Ensures no battery is present before applying power.  
- **Status Outputs:** Indicates charge state (charging, complete, or fault).  
- **Thermal Protection:** Reduces charge current if temperature exceeds safe limits.  
- **No External MOSFET or Diode Required:** Integrated design simplifies circuitry.  
- **Low Dropout Operation:** Efficient charging even with low input voltage.  

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