Description and Introduction

【1% Accuracy, Low-Power, +3V and +5V レP Supervisory Circuits The **MAX815N** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated**. Below are the key specifications, descriptions, and features based on the available knowledge:

### **Specifications:**
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** Adjustable or fixed (depends on variant)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 8-pin DIP, SOIC  
- **Manual Reset Input:** Available (active-low)  
- **Watchdog Timer:** Yes (in some variants)  
- **Power-Fail Comparator:** No  

### **Descriptions:**
- The **MAX815N** monitors microprocessor power supplies to ensure proper system operation.  
- It generates a reset signal if the supply voltage drops below a preset threshold, preventing erratic behavior.  
- Some variants include a watchdog timer to detect software crashes.  
- Designed for low-power applications with minimal current consumption.  

### **Features:**
1. **Precision Voltage Monitoring:** Ensures reliable reset generation.  
2. **Manual Reset Input:** Allows external reset triggering.  
3. **Low Quiescent Current:** Suitable for battery-powered systems.  
4. **Adjustable or Fixed Reset Threshold:** Configurable for different voltage levels.  
5. **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
6. **Industrial Temperature Range:** Operates reliably in harsh environments.  

For exact variant-specific details, refer to the official **Maxim Integrated datasheet**.
