Description and Introduction

Precision Quad Supply Monitor in 6-Lead SOT-23 The LTC2903IS6-D1#PBF is a precision triple power supply monitor manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 1.5V to 5.5V (per monitored supply)  
- **Threshold Accuracy:** ±1.5% (over temperature)  
- **Adjustable Reset Timeout:** 20ms to 1.2s (via external capacitor)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  
- **Supply Current:** 45µA (typical)  
- **Reset Output:** Active-low, push-pull  

### **Descriptions:**  
The LTC2903IS6-D1#PBF monitors three voltage rails and provides a reset signal if any of them fall below their respective threshold voltages. It is designed for precision monitoring in multi-voltage systems, ensuring reliable operation in applications such as microcontrollers, FPGAs, and DSPs.  

### **Features:**  
- Monitors three independent voltage rails  
- Adjustable reset timeout period  
- Low quiescent current (45µA typical)  
- Guaranteed operation down to 1.5V  
- No external resistors required for fixed threshold options  
- Small SOT-23-6 package  

This device ensures system integrity by providing a reliable reset signal during power-up, power-down, or brownout conditions.
