Description and Introduction

Advanced Chemistry-Independent, Level 2 Battery Charger with Input Current Limiting The MAX1645BEEI is a DC-DC converter IC manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1645BEEI  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Package:** 16-pin QSOP (QSOP-16)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX1645BEEI is a high-efficiency, low-voltage, step-up DC-DC converter designed for battery-powered applications. It is capable of generating a regulated output voltage from very low input voltages, making it suitable for single-cell or dual-cell battery systems.

### **Features:**
- **Low Start-Up Voltage:** Operates down to 0.7V input.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **High Efficiency:** Up to 90% power conversion efficiency.  
- **Internal Power MOSFET:** Eliminates the need for an external switch.  
- **Low Quiescent Current:** Typically 45µA for improved battery life.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Overcurrent Protection:** Safeguards against excessive load conditions.  
- **Compact Package:** 16-pin QSOP for space-constrained applications.
