Description and Introduction

High Input Voltage Charger The ISL6294IRZ is a lithium-ion battery charger IC manufactured by INTERSIL (now part of Renesas Electronics).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 6.5V  
- **Charge Voltage Accuracy:** ±0.5%  
- **Programmable Charge Current:** Up to 1.5A  
- **Battery Voltage Range:** 3.0V to 4.2V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QFN (4mm x 4mm)  

### **Descriptions:**  
- A standalone linear charger for single-cell Li-ion/Li-polymer batteries.  
- Features constant-current (CC) and constant-voltage (CV) charging modes.  
- Includes thermal regulation to prevent overheating.  

### **Features:**  
- **Automatic Charge Termination:** Stops charging when current drops below a preset threshold.  
- **Pre-Charge Conditioning:** Safely charges deeply discharged batteries.  
- **Charge Status Output:** Provides indication of charging state.  
- **Reverse Leakage Protection:** Prevents battery discharge when input power is removed.  
- **Soft-Start Function:** Limits inrush current during startup.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application circuits, refer to the official documentation.

Application Scenarios & Design Considerations
