Description and Introduction

Lithium-Ion Linear Battery Charger in ThinSOT The LTC1734LES6-4.2#PBF is a lithium-ion battery charger controller manufactured by Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Linear Technology (Analog Devices)  
- **Part Number:** LTC1734LES6-4.2#PBF  
- **Package:** SOT-23-6  
- **Input Voltage Range:** 4.5V to 22V  
- **Battery Voltage:** Fixed 4.2V (for single-cell Li-Ion)  
- **Charge Current:** Programmable up to 1.5A  
- **Charge Termination:** C/10 or Timer-Based  
- **Preconditioning Mode:** Yes (for deeply discharged batteries)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Status Indicators:** Charge Status Output (Open-Drain)  

### **Descriptions:**  
The LTC1734LES6-4.2#PBF is a standalone linear charger controller designed for single-cell lithium-ion batteries. It provides a complete charging solution with automatic charge termination, preconditioning, and fault protection. The device operates from a wide input voltage range and includes thermal regulation to prevent overheating.  

### **Features:**  
- **Standalone Operation:** No external microcontroller required.  
- **Programmable Charge Current:** Adjustable via an external resistor.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds safe limits.  
- **Automatic Recharge:** Initiates a new charge cycle if battery voltage drops.  
- **Low Battery Preconditioning:** Trickle charges deeply discharged cells before full-current charging.  
- **Charge Status Output:** Indicates charging, completion, or fault conditions.  
- **Reverse Battery Protection:** Prevents damage from reverse-connected battery.  

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