Description and Introduction

±1% Accuracy, Low-Power, +3V and +5V µP Supervisory Circuits The MAX815LESA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX815LESA+  
- **Type:** Microprocessor Supervisory Circuit  
- **Package:** 8-Pin SOIC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or Fixed (Factory-Set)  
- **Reset Timeout Period:** Typically 140ms (for fixed threshold versions)  
- **Watchdog Timer:** Yes (1.6s typical timeout)  
- **Manual Reset Input:** Yes (Active-Low)  
- **Power-On Reset (POR):** Yes  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX815LESA+ is a supervisory circuit designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal during power-up, power-down, or brownout conditions. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.  

### **Features:**  
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
- **Adjustable or Fixed Reset Threshold:** Available in factory-set or adjustable versions.  
- **Watchdog Timer:** Detects system failures by requiring periodic toggling.  
- **Manual Reset Input:** Allows external push-button reset.  
- **Low Quiescent Current:** Typically 50μA (reduces power consumption).  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable reset assertion.  
- **Small Form Factor:** 8-Pin SOIC package for space-constrained applications.  

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