Description and Introduction

SMBus Interfaced Battery Charger with Internal FETs The **ISL95871CHRZ** is a power management IC manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on available data:

### **Specifications:**
- **Manufacturer:** Intersil (Renesas Electronics)  
- **Package:** 48-Lead QFN (6x6mm)  
- **Input Voltage Range:** 4.5V to 25V  
- **Output Voltage Range:** Programmable (supports multiple phases)  
- **Switching Frequency:** Adjustable (typically up to 1MHz)  
- **Number of Phases:** Supports 2-phase operation  
- **Control Method:** Voltage-mode PWM controller  
- **Operating Temperature Range:** -40°C to +85°C  
- **Protection Features:** Overcurrent, overvoltage, undervoltage, and thermal shutdown  

### **Descriptions:**
The **ISL95871CHRZ** is a high-efficiency, multi-phase PWM controller designed for **CPU/GPU power delivery** in notebooks and other computing applications. It integrates **adaptive voltage positioning (AVP)** and supports **dynamic phase shedding** to optimize efficiency across load conditions.

### **Features:**
- **Multi-Phase Operation:** Supports 2-phase synchronous buck converter configurations.  
- **Adaptive Voltage Positioning (AVP):** Enhances transient response and reduces output capacitance.  
- **Dynamic Phase Shedding:** Improves efficiency at light loads by disabling phases.  
- **Programmable Switching Frequency:** Adjustable up to 1MHz for optimized performance.  
- **Integrated MOSFET Drivers:** Supports high-side and low-side N-channel MOSFETs.  
- **Digital Power Management:** Compatible with SMBus/I²C for system monitoring and control.  
- **Protection Mechanisms:** Includes OCP, OVP, UVP, and thermal shutdown.  

This IC is commonly used in **laptop power systems** and other applications requiring precise voltage regulation.
