Description and Introduction

Low-Cost, µP Supervisory Circuits The **MAX813LESA+** is a microprocessor supervisory circuit manufactured by **MAXIM** (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 (Analog Devices)  
- **Type:** Microprocessor Supervisor  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (4.38V, 4.63V, etc.)  
- **Reset Timeout Period:** 140ms (typical)  
- **Watchdog Timer:** 1.6s (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Manual Reset Input:** Yes (active-low)  
- **Power-Fail Comparator:** No  
- **Output Type:** Active-low reset  

### **Descriptions:**  
The **MAX813LESA+** is designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal if the supply voltage drops below a preset threshold. It includes a watchdog timer to detect software lockups and a manual reset input for external control.  

### **Features:**  
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
- **Reset Output:** Active-low reset signal during power-up, power-down, or brownout conditions.  
- **Watchdog Timer:** Detects system lockups; requires periodic toggling to prevent reset.  
- **Manual Reset Input:** Allows external pushbutton reset.  
- **Low Power Consumption:** Minimal current draw for battery-operated systems.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V operation.  
- **Industrial Temperature Range:** Suitable for harsh environments (-40°C to +85°C).  

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