Description and Introduction

Highly Integrated Battery Charger Controller for Notebook Computers The ISL6252AHAZ is a battery charger controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on available factual information:

### **Specifications:**
- **Manufacturer:** INTERSIL  
- **Part Number:** ISL6252AHAZ  
- **Package:** 28-lead QFN (Quad Flat No-Lead)  
- **Input Voltage Range:** 7V to 25V  
- **Charge Voltage Accuracy:** ±0.5%  
- **Charge Current Accuracy:** ±3%  
- **Switching Frequency:** Adjustable (typically 300kHz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Control Method:** PWM (Pulse-Width Modulation)  

### **Descriptions:**
- The ISL6252AHAZ is a highly integrated battery charger controller designed for Li-ion/Li-polymer battery packs.  
- It supports 2 to 4 series cells with programmable charge voltage and current.  
- Includes adaptive input current limiting to prevent overloading the AC adapter.  
- Provides safety features such as overvoltage, overcurrent, and thermal protection.  

### **Features:**
- **Wide Input Voltage Range:** Supports 7V to 25V input.  
- **Precision Charging:** High-accuracy voltage (±0.5%) and current (±3%) regulation.  
- **AC Adapter Detection:** Automatically detects and adjusts input current limit.  
- **Programmable Charge Parameters:** Adjustable charge voltage (up to 19.2V) and current.  
- **Power Good Indicator:** Monitors input voltage and charger status.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds safe limits.  
- **Low Power Consumption:** Supports low quiescent current in standby mode.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official datasheet from Renesas Electronics (formerly INTERSIL).
