Description and Introduction

Precision Triple/Dual Input UV, OV and Negative Voltage Monitor The LTC2909IDDB-3.3 is a precision triple supply monitor manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 36V  
- **Threshold Accuracy:** ±1.5% (over temperature)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead DFN (3mm × 2mm)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (200ms typical)  
- **Quiescent Current:** 25µA (typical)  
- **Output Type:** Active-low reset (open-drain)  

### **Descriptions:**  
The LTC2909IDDB-3.3 monitors three positive voltage rails and generates a reset signal if any of the supplies fall below their respective thresholds. It is designed for high-accuracy monitoring in systems requiring reliable power supervision.  

### **Features:**  
- **Triple Voltage Monitoring:** Tracks three independent power supplies.  
- **Adjustable or Fixed Reset Timeout:** Configurable via an external capacitor.  
- **Wide Input Voltage Range:** Supports monitoring from 2.7V to 36V.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **High Accuracy:** ±1.5% threshold accuracy ensures precise monitoring.  
- **Open-Drain Reset Output:** Compatible with multiple logic levels.  
- **Small Form Factor:** 8-Lead DFN package for space-constrained designs.  

This device is commonly used in industrial, automotive, and embedded systems where reliable power supply monitoring is critical.
