Description and Introduction

USB Compatible Lithium-Ion Battery Charger with Thermal Regulation The LTC4053EMSE-4.2#PBF is a lithium-ion battery charger IC manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.25V to 6.5V  
- **Charge Voltage:** 4.2V (fixed)  
- **Charge Current:** Up to 500mA (programmable)  
- **Termination Method:** C/10 (10% of programmed current)  
- **Preconditioning:** Yes (for deeply discharged batteries)  
- **Charge Status Outputs:** Yes (open-drain outputs for charging and power good)  
- **Package:** MSOP-10  
- **Operating Temperature Range:** -40°C to +85°C  
- **Thermal Regulation:** Yes (prevents overheating)  

### **Descriptions:**  
The LTC4053EMSE-4.2#PBF is a standalone linear charger designed for single-cell lithium-ion/polymer batteries. It integrates a complete charging solution with thermal regulation, charge termination, and status monitoring.  

### **Features:**  
- **Standalone Operation:** No external microcontroller required.  
- **Programmable Charge Current:** Set via an external resistor.  
- **Thermal Regulation:** Reduces charge current if temperature rises.  
- **Automatic Recharge:** Initiates charging if battery voltage falls below 4.1V.  
- **Low Battery Leakage:** <1µA when input power is removed.  
- **Battery Detection:** Ensures no battery is present before charging.  
- **Small Footprint:** MSOP-10 package for space-constrained applications.
