Description and Introduction

Stand-Alone Switch-Mode Lithium-Ion Battery-Charger Controller The MAX1737EEI is a lithium-ion (Li+) battery charger controller manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 28V  
- **Battery Voltage Range:** 2.5V to 4.2V (adjustable)  
- **Charge Current:** Programmable up to 4A  
- **Charge Termination:** Voltage and current-based  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin QSOP (EEI package)  

### **Descriptions:**
- The MAX1737EEI is a high-efficiency, switch-mode battery charger controller designed for single-cell Li+ batteries.  
- It supports constant-current (CC) and constant-voltage (CV) charging modes.  
- Includes thermal regulation to prevent overheating.  
- Features an integrated MOSFET driver for external N-channel FETs.  

### **Features:**
- **Programmable Charge Current:** Adjustable via an external resistor.  
- **Input Overvoltage Protection (OVP):** Safeguards against excessive input voltage.  
- **Battery Detection:** Automatically detects battery presence.  
- **Charge Status Outputs:** Provides LED or logic signals for charge status.  
- **Low Dropout Operation:** Maximizes efficiency.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds safe limits.  

This device is commonly used in portable electronics, power tools, and other applications requiring efficient Li+ battery charging.
