Description and Introduction

Lithium-Ion Linear Battery Charger in ThinSOT The LTC1734LES6-42 is a linear battery charger controller manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Linear Technology (LINTER)  
- **Part Number:** LTC1734LES6-42  
- **Package:** SOT-23-6  
- **Input Voltage Range:** 4.5V to 28V  
- **Charge Voltage:** 4.2V (fixed for single-cell Li-Ion batteries)  
- **Charge Current:** Programmable via external resistor  
- **Charge Termination:** C/10 or timer-based  
- **Preconditioning:** For deeply discharged cells  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The LTC1734LES6-42 is a standalone linear charger controller designed for single-cell Lithium-Ion (Li-Ion) or Lithium-Polymer (Li-Po) batteries.  
- It provides a constant-current/constant-voltage (CC/CV) charging profile with automatic termination.  
- The device includes safety features such as thermal shutdown and bad battery detection.  

### **Features:**
- **Standalone Operation:** No external microcontroller required.  
- **Programmable Charge Current:** Set via an external resistor.  
- **Automatic Recharge:** Initiates charging if battery voltage falls below a threshold.  
- **Thermal Regulation:** Reduces charge current if temperature rises excessively.  
- **Low Dropout Voltage:** Allows efficient charging even with lower input voltages.  
- **Battery Detection:** Prevents charging if no battery is present.
