Description and Introduction

Compact / High-Efficiency / Dual-Output Step-Up DC-DC Converter The MAX1817EUB is a USB-powered Li+ battery charger from Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX1817EUB  
- **Package:** 10-pin µMAX (µSOP)  
- **Input Voltage Range:** 4.35V to 6.5V (USB-compatible)  
- **Charge Voltage:** 4.1V or 4.2V (selectable)  
- **Charge Current:** Programmable up to 500mA  
- **Charge Termination:** Automatic (based on current threshold)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MAX1817EUB is a linear Li+ battery charger designed for USB-powered applications.  
- It provides a complete charging solution with thermal regulation, charge current limiting, and automatic charge termination.  
- The device can be configured for either 4.1V or 4.2V charge voltage, depending on battery requirements.  
- It includes undervoltage lockout (UVLO) and thermal shutdown protection.  

### **Features:**  
- **USB-Compatible Input:** Works with standard USB power sources.  
- **Programmable Charge Current:** Adjustable via an external resistor.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds safe limits.  
- **Charge Status Outputs:** Indicates charging, fault, and power-good conditions.  
- **Low Battery Leakage:** Minimizes battery drain when not charging.  
- **Automatic Recharge:** Restarts charging if battery voltage falls below a threshold.  

The MAX1817EUB is commonly used in portable devices requiring USB-based battery charging.
