Negative Voltage Diode-OR Controller and Monitor

Partnumber Manufacturer Quantity Availability
LTC4354IDDB LINEAR 111 In Stock

Description and Introduction

Negative Voltage Diode-OR Controller and Monitor The LTC4354IDDB is a positive high voltage ideal diode controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Package:** DFN-8 (3mm x 3mm)  
- **Operating Voltage Range:** 4V to 80V  
- **Maximum Forward Voltage Drop:** Low (depends on external MOSFET)  
- **Reverse Leakage Current:** Typically 1µA  
- **Operating Temperature Range:** -40°C to 125°C  
- **Switching Speed:** Adjustable via external capacitor  

### **Descriptions:**  
The LTC4354IDDB is designed to control an external N-channel MOSFET to emulate an ideal diode, minimizing power loss and voltage drop. It is used in applications requiring reverse polarity protection, ORing diodes, and load sharing.  

### **Features:**  
- **Ideal Diode Operation:** Replaces Schottky diodes with lower loss.  
- **Adjustable Turn-On Speed:** Controlled via an external capacitor.  
- **Fast Turn-Off:** Prevents reverse current flow.  
- **Wide Input Range:** Supports 4V to 80V operation.  
- **Low Quiescent Current:** Typically 200µA.  
- **Fault Protection:** Includes overvoltage and undervoltage lockout.  

This information is based on the manufacturer's datasheet.
