Description and Introduction

Full-featured microprocessor supervisory circuit with +-1.5% reset accuracy. Reset threshold (typ) 4.575V The MAX807NCWE is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX807NCWE  
- **Package:** 16-SOIC (Wide)  
- **Type:** Microprocessor Supervisor  
- **Voltage - Threshold:** 4.38V  
- **Number of Voltages Monitored:** 1  
- **Output Type:** Active Low, Push-Pull  
- **Reset Timeout:** 140ms (Minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (Vcc):** 1V to 5.5V  

### **Descriptions:**
The MAX807NCWE is a precision voltage monitor designed to monitor system power supply voltages in microprocessor-based systems. It provides a reset signal to the μP during power-up, power-down, or brownout conditions, ensuring proper system operation.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation at a fixed threshold of 4.38V.  
- **Manual Reset Input:** Allows for external pushbutton reset control.  
- **140ms Minimum Reset Pulse Width:** Guarantees sufficient time for system initialization.  
- **Low Power Consumption:** Typically draws 20μA supply current.  
- **Push-Pull RESET Output:** No external pull-up resistor required.  
- **Wide Operating Voltage Range:** Works from 1V to 5.5V.  
- **Industrial Temperature Range:** Operates from -40°C to +85°C.  

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