### **Specifications:**  
- **Input Voltage Range (DCIN/USBIN):** 4V to 7V (DCIN), 4V to 6V (USBIN)  
- **Charge Voltage:** 4.2V (adjustable with external resistors)  
- **Charge Current:** Up to 500mA (programmable)  
- **Battery Type:** Single-cell Li-ion/Li-polymer  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin TQFN (5mm x 5mm)  
- **Integrated Features:** Thermal regulation, input current limiting, and charge termination  

### **Descriptions:**  
- The MAX1559ETE is designed for dual-input charging (DC adapter and USB port).  
- It automatically selects the appropriate power source (DCIN or USBIN).  
- Includes thermal regulation to prevent overheating.  

### **Features:**  
- **Dual-Input Charging:** Supports DC adapter and USB power sources.  
- **Programmable Charge Current:** Adjustable via external resistor.  
- **Automatic Power Source Selection:** Prioritizes DCIN when both inputs are present.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds safe limits.  
- **Charge Status Indicators:** Open-drain outputs for charging and power-good status.  
- **Low Battery Leakage:** Minimizes battery drain when no input power is present.
