Description and Introduction

Precision quad supply monitor. The LTC2903CS6-B1 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  
- **Threshold Accuracy:** ±1.5% (over temperature)  
- **Supply Current:** 10µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  
- **Adjustable or Fixed Threshold Options:** Fixed or resistor-programmable  
- **Reset Output:** Open-drain (active-low)  
- **Power-On Reset Delay:** Adjustable via external capacitor  

### **Descriptions:**  
The LTC2903CS6-B1 monitors three power supply voltages and provides a reset signal if any of the supplies fall below their respective thresholds. It is designed for precision monitoring in multi-voltage systems, ensuring reliable operation.  

### **Features:**  
- Monitors three voltage rails  
- Adjustable reset timeout  
- Low quiescent current  
- Guaranteed operation down to 1V  
- Small SOT-23-6 package  
- No external resistors required for fixed threshold versions  

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

(Note: Always refer to the latest datasheet for updated specifications.)

Application Scenarios & Design Considerations

Precision quad supply monitor.

Alternative Part Number

  • MAX6710KUT-T --: Quad voltage supervisor with similar monitoring thresholds and open-drain reset outputs, suitable drop-in replacement for supply rail supervision.
  • ADM1184ARMZ --: Quad voltage monitor/supervisor in a small package with adjustable thresholds, functionally comparable to the LTC2903 family.
  • TPS3700DDCR --: Wide-supply window voltage supervisor with adjustable thresholds and open-drain output, usable as an alternative for multi-rail monitoring.
  • MAX6710AUT-T --: Quad voltage supervisor with similar monitoring thresholds and open-drain reset, a direct functional substitute for the LTC2903 in SOT-23 packages.
  • TPS3703A01DRYR --: Multi-channel voltage supervisor with adjustable thresholds and reset output, suitable replacement for supply monitoring applications.
