Description and Introduction

Precision Triple/Dual Input UV, OV and Negative Voltage Monitor The LTC2909ITS8-3.3#PBF is a precision triple supply monitor manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC2909ITS8-3.3#PBF  
- **Package:** TSOT-8  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage Range:** 1.5V to 5.5V  
- **Threshold Voltage:** 3.3V (fixed)  
- **Accuracy:** ±1.5% over temperature  
- **Quiescent Current:** 8µA (typical)  
- **Reset Timeout Period:** Adjustable via external capacitor  
- **Output Type:** Active-low reset (open-drain)  

### **Descriptions:**  
The LTC2909ITS8-3.3#PBF is a triple supply voltage monitor designed to supervise three voltage rails. It ensures system reliability by monitoring voltages and generating a reset signal if any of the supplies fall below their threshold.  

### **Features:**  
- Monitors three voltage rails (V1, V2, V3)  
- Fixed 3.3V threshold for one supply, adjustable thresholds for the other two  
- Open-drain reset output with adjustable delay  
- Low quiescent current (8µA typical)  
- Guaranteed operation from 1.5V to 5.5V  
- ±1.5% threshold accuracy over temperature  
- Small TSOT-8 package  
- Ideal for microprocessor and FPGA power monitoring  

This device is commonly used in applications requiring reliable power supply monitoring, such as embedded systems, industrial controls, and communication equipment.
