Description and Introduction

+-1% accuracy, low-power, microprocessor supervisory circuit. Reset trip threshold (min) 4.50V (max) 4.60V, push-pull active-low reset output, manual reset, power-fail monitor, watchdog circuit. The MAX815NESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX815NESA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set at 4.65V for 5V systems)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 12μA (typical)  

### **Descriptions:**  
The MAX815NESA is a low-power microprocessor supervisory circuit designed to monitor power supply voltages in digital systems. It ensures proper system operation by generating a reset signal when the supply voltage falls below a preset threshold. It is commonly used in embedded systems, industrial controls, and battery-powered applications.  

### **Features:**  
- **Precision Voltage Monitoring:** Monitors VCC and asserts reset when voltage drops below threshold.  
- **Manual Reset Input:** Allows for external pushbutton reset control.  
- **Low Power Consumption:** Typically draws only 12μA, making it suitable for battery-powered devices.  
- **Guaranteed Reset Output Valid Down to VCC = 1V:** Ensures reliable reset even during brownout conditions.  
- **No External Components Required:** Simplifies circuit design.  
- **8-Pin SOIC Package:** Compact and space-efficient.  

This information is based solely on the manufacturer's datasheet and technical documentation.
