Description and Introduction

Hot Swappable Load Share Controller The **LTC4350IGN#PBF** is a **Hot Swap Controller** manufactured by **Linear Technology (now part of Analog Devices)**.  

### **Key Specifications:**  
- **Input Voltage Range:** 9V to 80V  
- **Operating Supply Current:** 400µA (typical)  
- **Fault Current Threshold:** Adjustable via external sense resistor  
- **Gate Drive Voltage:** Adjustable for N-channel MOSFET control  
- **Overvoltage Protection (OVP) Threshold:** Adjustable via external resistors  
- **Undervoltage Lockout (UVLO):** Adjustable via external resistors  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP  

### **Descriptions:**  
The LTC4350 is a **positive voltage hot swap controller** designed to safely manage the insertion and removal of circuit boards from live backplanes. It prevents excessive inrush current and protects against overvoltage conditions.  

### **Features:**  
- **Controls N-Channel MOSFETs** for smooth power-up  
- **Adjustable current limit** using an external sense resistor  
- **Fast response** to short-circuit and overcurrent events  
- **Adjustable OVP and UVLO** thresholds  
- **Reverse input protection**  
- **Low quiescent current** (400µA typical)  
- **Fault timer** for latch-off or auto-retry modes  

This device is commonly used in **telecom, industrial, and server applications** for safe hot-swapping of high-voltage power supplies.
