Description and Introduction

Precision Dual Supply Monitors with One Pin-Selectable Threshold and One Adjustable Input The LTC2907CDDB is a precision triple power supply monitor manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Package:** DFN-8 (3mm x 3mm)  
- **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:** 25µA (typical)  

### **Descriptions and Features:**  
- Monitors three positive power supply voltages with adjustable thresholds.  
- Provides a single active-low reset output when any monitored supply falls below its threshold.  
- Adjustable reset timeout delay (via an external capacitor).  
- Low quiescent current makes it suitable for battery-powered applications.  
- Guaranteed accuracy over the full temperature range.  
- Small DFN package for space-constrained applications.  

The LTC2907CDDB is commonly used in systems requiring reliable power supply monitoring, such as embedded systems, industrial controls, and communication equipment.
