Description and Introduction

Programmable Quad Supply Monitor with Adjustable Reset and Watchdog Timers The LTC2901-1CGN is a precision triple power supply monitor manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 1.2V to 5V (adjustable via external resistors)  
- **Threshold Accuracy:** ±1.5% (over temperature)  
- **Supply Current:** 20µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP  
- **Reset Timeout Period:** Adjustable via external capacitor  
- **Manual Reset Input:** Active-low with internal pull-up  
- **Output:** Active-low open-drain reset output  

### **Descriptions:**  
The LTC2901-1CGN monitors three power supply voltages and generates a reset signal if any of them fall below their respective thresholds. It is designed for precision monitoring in multi-voltage systems, ensuring reliable operation.  

### **Features:**  
- Monitors three voltage rails with adjustable thresholds  
- ±1.5% threshold accuracy over temperature  
- Low 20µA supply current  
- Adjustable reset timeout period  
- Manual reset capability  
- Open-drain reset output  
- Wide operating temperature range (-40°C to +85°C)  
- Small 16-Lead SSOP package  

This device is commonly used in applications requiring reliable power monitoring, such as embedded systems, servers, and industrial equipment.
