Description and Introduction

Full-featured microprocessor supervisory circuit with +-1.5% reset accuracy. Reset threshold (typ) 4.425V The MAX807MEWE is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX807MEWE  
- **Package:** 16-SOIC (Wide)  
- **Type:** Microprocessor Supervisor  
- **Operating Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some variants)  
- **Output Type:** Active-low or active-high reset output  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Low (typically a few µA)  

### **Descriptions:**
- The MAX807MEWE monitors system voltage and provides a reset signal to a microprocessor 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.  
- Available in fixed or adjustable threshold versions for flexibility in different applications.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Manual Reset Input:** Allows for external reset triggering.  
- **Wide Operating Voltage Range:** Compatible with various logic levels.  
- **Industrial Temperature Range:** Suitable for harsh environments.  
- **Small Footprint:** 16-SOIC package for space-constrained designs.  

This device is commonly used in embedded systems, industrial controls, and automotive applications where reliable power monitoring is critical.  

(Note: For exact threshold values, timing, and other detailed specifications, refer to the official datasheet.)
