Description and Introduction

Hot swap controller The LTC1421IG is a product from LINEAR (Linear Technology). Here are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC1421IG  
- **Type:** Hot Swap Controller  
- **Package:** SSOP-24  
- **Operating Voltage Range:** 2.7V to 15V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Current Limit Adjustable:** Yes  
- **Fault Protection Features:** Overcurrent, Undervoltage, Overvoltage  
- **Power Good Output:** Yes  

### **Descriptions:**
The LTC1421IG is a hot swap controller designed to safely insert and remove boards from live backplanes. It provides inrush current control, fault protection, and power monitoring. The device ensures smooth power-up and protects against short circuits and voltage transients.

### **Features:**
- **Adjustable Current Limit:** Allows precise control over inrush current.  
- **Undervoltage Lockout (UVLO):** Prevents operation below a safe voltage threshold.  
- **Overvoltage Protection (OVP):** Shuts down the circuit if voltage exceeds a set limit.  
- **Power Good Indicator:** Signals when the output voltage is within regulation.  
- **Fault Timer:** Provides a delay before shutting down in fault conditions.  
- **Wide Operating Voltage Range:** Supports 2.7V to 15V applications.  
- **SSOP-24 Package:** Compact and suitable for space-constrained designs.  

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