Description and Introduction

Hot Swap Controller with Multifunction Current Control The LTC4211CMS is a hot swap controller manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC4211CMS  
- **Package:** MSOP-10  
- **Operating Voltage Range:** 2.9V to 15V  
- **Current Limit Range:** Adjustable  
- **Gate Drive Voltage:** 5V (for external N-channel MOSFET)  
- **Fault Response:** Auto-retry or latch-off mode  
- **Operating Temperature Range:** -40°C to 85°C  

### **Descriptions:**  
The LTC4211CMS is a hot swap controller designed to safely insert and remove boards from live backplanes. It provides inrush current control, short-circuit protection, and undervoltage/overvoltage monitoring. It drives an external N-channel MOSFET to regulate power delivery.  

### **Features:**  
- **Adjustable Current Limit:** Uses an external sense resistor.  
- **Fast Response:** Protects against short circuits in microseconds.  
- **Programmable Fault Timer:** Prevents nuisance tripping.  
- **Undervoltage Lockout (UVLO):** Ensures proper supply voltage before turn-on.  
- **Auto-Retry or Latch-Off Mode:** Configurable fault response.  
- **Power Good Output:** Indicates valid operating conditions.  
- **Low Quiescent Current:** Minimizes power consumption.  

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