Description and Introduction

+5V Microprocessor Supervisory Circuits The MAX817LESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Series:** MAX817  
- **Package:** 8-SOIC (150 mil)  
- **Type:** Supervisor  
- **Number of Voltages Monitored:** 1  
- **Voltage - Threshold:** 4.38V  
- **Output:** Active-Low, Push-Pull  
- **Reset Timeout:** 140ms (Minimum)  
- **Operating Temperature:** -40°C to +85°C  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The MAX817LESA is a precision voltage monitor designed to ensure proper system operation in μP and digital systems. It monitors the power supply voltage and asserts a reset signal if the voltage drops below a preset threshold, ensuring a controlled system reset.  

### **Features:**  
- **Precision Voltage Monitoring:** Guarantees accurate reset threshold detection.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **140ms Minimum Reset Pulse Width:** Ensures reliable system reset.  
- **Active-Low RESET Output:** Push-pull configuration for direct interfacing with μP reset inputs.  
- **Low Power Consumption:** Typically 35μA supply current.  
- **Wide Operating Voltage Range:** 1.2V to 5.5V.  
- **No External Components Required:** Simplifies design and reduces board space.  
- **Industrial Temperature Range:** Operates from -40°C to +85°C.  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications requiring reliable power monitoring.
