Description and Introduction

High Side Driver, N-Channel MOSFET, Bootstrap Supply The ISL6801AB is a digital PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V (VDD)  
- **Output Voltage Range:** Programmable via digital interface  
- **Switching Frequency:** Configurable up to 2MHz  
- **Number of PWM Outputs:** 6  
- **Control Interface:** PMBus™ compliant (I²C-based)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** 32-Lead QFN (5mm x 5mm)  

### **Descriptions:**  
- The ISL6801AB is a digital multiphase PWM controller designed for high-performance voltage regulation in power supply applications.  
- It supports PMBus communication for real-time monitoring and configuration of power parameters.  
- Optimized for synchronous buck converters, it enables precise voltage regulation and dynamic phase control.  

### **Features:**  
- **Digital Control Loop:** Enables adaptive voltage positioning (AVP) and dynamic phase shedding.  
- **PMBus Compliance:** Allows for programmable voltage, current limits, and fault management.  
- **Multiphase Operation:** Supports up to 6 phases with automatic phase balancing.  
- **Protection Features:** Overvoltage (OVP), undervoltage (UVP), overcurrent (OCP), and overtemperature (OTP) protection.  
- **Non-Volatile Memory (NVM):** Stores configuration settings for quick startup.  
- **Differential Remote Sensing:** Ensures accurate output voltage regulation.  

This information is based on the manufacturer's datasheet and technical documentation.
