Description and Introduction

Precision Triple/Dual Input UV, OV and Negative Voltage Monitor The LTC2909CTS8-2.5#PBF is a precision dual supply monitor manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Part Number:** LTC2909CTS8-2.5#PBF  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Package:** TSOT-8  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage Range (VCC):** 2.7V to 36V  
- **Threshold Voltage:** 2.5V (fixed)  
- **Accuracy:** ±1.5% (over temperature)  
- **Quiescent Current:** 20μA (typical)  
- **Reset Timeout Period:** Adjustable via external capacitor (default 200ms)  
- **Output Type:** Active-low, open-drain RESET  
- **Number of Monitored Supplies:** Dual (VCC and auxiliary input)  

### **Descriptions:**  
The LTC2909 is a dual supply voltage monitor designed to ensure proper system operation by monitoring two power supply rails. It features a fixed threshold for the primary supply (VCC) and an adjustable threshold for the auxiliary input. The device provides an active-low RESET signal when either supply falls below its threshold, ensuring reliable system initialization.  

### **Features:**  
- Monitors two power supplies (VCC and auxiliary input)  
- Fixed 2.5V threshold for VCC  
- Adjustable threshold for auxiliary input (via external resistors)  
- Low quiescent current (20μA typical)  
- Open-drain RESET output  
- Adjustable reset timeout (200ms default)  
- Wide operating voltage range (2.7V to 36V)  
- High accuracy (±1.5%)  
- Small TSOT-8 package  

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