Description and Introduction

Precision Dual Supply Monitors with Pin-Selectable Thresholds The LTC2905IDDB is a precision triple power supply monitor manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC2905IDDB  
- **Package:** DFN-8  
- **Operating Voltage Range:** 1.5V to 5.5V  
- **Number of Monitored Supplies:** 3  
- **Adjustable Threshold Voltages:** Yes (via external resistors)  
- **Accuracy:** ±1.5% over temperature  
- **Reset Timeout Period:** Adjustable (via external capacitor)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 40µA (typical)  

### **Descriptions:**  
The LTC2905IDDB is designed to monitor three voltage rails, ensuring they remain within specified thresholds. It provides a reset signal if any of the monitored voltages fall outside their set limits, making it suitable for systems requiring reliable power supervision.  

### **Features:**  
- Monitors three positive voltage supplies  
- Adjustable reset timeout delay  
- Low quiescent current  
- Guaranteed reset output for VCC ≥ 1V  
- No external voltage reference required  
- Small DFN-8 package  

For detailed specifications, refer to the official datasheet from Analog Devices (formerly Linear Technology).
