Description and Introduction

Dynamically-Adjustable / Synchronous Step-Down Controller with Integrated Voltage Positioning The MAX1813EEI is a battery-charging controller IC manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
Maxim Integrated  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Battery Voltage Range:** 3.5V to 18V  
- **Charging Current:** Programmable up to 4A  
- **Charging Accuracy:** ±0.5%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin QSOP (EEI)  

### **Descriptions:**  
The MAX1813EEI is a high-efficiency, switch-mode battery charger controller designed for single-cell or multi-cell Li-ion/Li-polymer batteries. It supports constant-current (CC) and constant-voltage (CV) charging modes and includes thermal regulation to prevent overheating.  

### **Features:**  
- **Programmable Charge Current:** Adjustable via an external resistor.  
- **Wide Input Voltage Range:** Supports various power sources, including AC adapters and USB.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds safe limits.  
- **Charge Termination:** Automatically stops charging when the battery reaches full capacity.  
- **Reverse Battery Protection:** Safeguards against incorrect battery connections.  
- **Low Dropout Operation:** Efficient charging even with small input-output differentials.  
- **Status Indicators:** Provides LED or logic outputs for charge status.  

This information is based solely on the manufacturer's datasheet for the MAX1813EEI.
