Description and Introduction

Precision Quad Supply Monitor in 6-Lead SOT-23 The LTC2903CS6-D1 is a precision triple power supply monitor manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Linear Technology (LT)  
- **Part Number:** LTC2903CS6-D1  
- **Package:** SOT-23-6  
- **Operating Voltage Range:** 1.5V to 5.5V  
- **Threshold Accuracy:** ±1.5% (typical)  
- **Supply Current:** 20µA (typical)  
- **Temperature Range:** -40°C to +85°C  
- **Reset Timeout Period:** Adjustable via external capacitor  
- **Output Type:** Active-low reset  

### **Descriptions:**  
The LTC2903CS6-D1 monitors three voltage rails and provides a reset signal if any of them fall below their programmed threshold. It is designed for precision monitoring in multi-voltage systems, ensuring reliable operation in applications such as microprocessors, FPGAs, and embedded systems.  

### **Features:**  
- Monitors three independent voltage rails  
- Adjustable reset timeout period  
- Low quiescent current (20µA typical)  
- Wide operating voltage range (1.5V to 5.5V)  
- High threshold accuracy (±1.5%)  
- Small SOT-23-6 package  
- Guaranteed operation from -40°C to +85°C  

This information is based solely on the device's datasheet and manufacturer specifications.

Application Scenarios & Design Considerations

Precision Quad Supply Monitor in 6-Lead SOT-23

Alternative Part Number

  • MAX6710AUTZD1-T --: Quad voltage supervisor with similar reset threshold and open-drain output, pin-compatible SOT-23-6 footprint and widely available as a direct functional substitute.
  • TPS3700DDCR --: Dual/quad window supervisor in SOT-23-6 with adjustable thresholds, low supply current, and similar reset timing suitable for replacing the LTC2903 monitor function.
  • ADM1184ARMZ --: Quad voltage monitor with open-drain reset outputs and similar threshold accuracy, offering a comparable supervisory function in a small package.
  • ADM1184ARMZ-1 --: Quad supply monitor with adjustable thresholds and reset output, functionally comparable to the LTC2903-D1.
