Description and Introduction

Stand-Alone Switch-Mode Lithium-Ion Battery-Charger Controller The MAX1737 is a lithium-ion (Li+) battery charge controller manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Charge Voltage Accuracy:** ±0.75%  
- **Programmable Charge Current:** Up to 4A  
- **Battery Voltage Range:** 2.5V to 4.2V (adjustable)  
- **Charge Termination:** User-selectable (C/10 or timer)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QSOP  

### **Descriptions:**  
- The MAX1737 is a high-efficiency, switch-mode battery charger designed for single-cell Li+ batteries.  
- It integrates a synchronous buck converter for efficient power conversion.  
- The device supports both constant-current (CC) and constant-voltage (CV) charging modes.  
- It includes thermal regulation to prevent overheating.  

### **Features:**  
- **Adjustable Output Voltage:** Supports different Li+ battery chemistries.  
- **Input Current Limiting:** Protects against excessive input current.  
- **Automatic Recharge:** Initiates charging if battery voltage drops below a threshold.  
- **Power-Good (PG) Output:** Indicates charging status.  
- **Low Battery Detection:** Monitors battery voltage for undervoltage conditions.  
- **Thermal Shutdown:** Protects the IC from overheating.  

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