Description and Introduction

Hot Swap Controller with Power-Up Timeout The **LTC4212IMS#PBF** 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 Technology (Analog Devices)  
- **Package:** MSOP-10  
- **Operating Voltage Range:** 2.9V to 15V  
- **Gate Drive Voltage:** Adjustable  
- **Current Limit Range:** Programmable via external sense resistor  
- **Fault Response:** Latch-off or auto-retry options  
- **Operating Temperature Range:** -40°C to +85°C  
- **Power Good Output:** Yes (open-drain)  
- **Quiescent Current:** Typically 200µA  

### **Descriptions:**
The **LTC4212IMS#PBF** is a **hot swap controller** designed to safely insert and remove boards from live backplanes. It provides inrush current control, short-circuit protection, and overcurrent monitoring. The device allows smooth power-up by controlling an external N-channel MOSFET and includes programmable fault response.

### **Features:**
- **Inrush Current Control:** Limits surge current during power-up  
- **Programmable Current Limit:** Adjustable via an external sense resistor  
- **Fast Overcurrent Protection:** Responds quickly to short circuits  
- **Adjustable Fault Timer:** Configurable for latch-off or auto-retry modes  
- **Power Good Indicator:** Open-drain output signals valid supply voltage  
- **Wide Operating Voltage Range:** Supports 2.9V to 15V applications  
- **Low Quiescent Current:** Minimizes power consumption  

This device is commonly used in **servers, telecom systems, and hot-swappable boards** to ensure safe power management.
