Description and Introduction

+5V Microprocessor Supervisory Circuits The MAX819LESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX819LESA  
- **Type:** Microprocessor Supervisor  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** Adjustable or fixed (depending on variant)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The MAX819LESA monitors system voltage and provides a reset signal to the μP or microcontroller when the supply voltage falls below a preset threshold.  
- It ensures proper system initialization by holding the reset signal active until the supply voltage stabilizes.  
- Suitable for battery-powered and low-voltage applications due to its wide operating range.  

### **Features:**
- **Low Quiescent Current:** Typically 5μA, making it ideal for power-sensitive designs.  
- **Manual Reset Input:** Allows for external reset control.  
- **Power-On Reset (POR) Circuitry:** Ensures a valid reset signal upon power-up.  
- **Watchdog Timer (WDT) Option:** Available in some variants for system fault detection.  
- **Small Form Factor:** 8-pin SOIC package for space-constrained applications.
