Description and Introduction

Full-featured microprocessor supervisory circuit with +-1.5% reset accuracy. Reset threshold (typ) 4.675V The **MAX807LCWE** 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  
- **Package:** 16-pin Wide SOIC (SOIC-16)  
- **Type:** µP Supervisory Circuit  
- **Voltage Monitoring:** Monitors 3.3V, 5V, or adjustable voltage rails  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** Adjustable or fixed (typically 140ms or 280ms)  
- **Operating Voltage Range:** 1V to 5.5V  
- **Quiescent Current:** Low (typically 6µA)  
- **Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**  
The MAX807LCWE is designed to monitor system power supplies and provide a reset signal to microprocessors or other digital systems during power-up, power-down, or brownout conditions. It ensures reliable operation by holding the µP in reset until the supply voltage stabilizes.  

### **Features:**  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Power-On Reset (POR):** Guarantees a reset pulse upon power-up.  
- **Watchdog Timer:** Monitors µP activity and triggers reset if the µP fails to toggle within a set time.  
- **Low-Power Operation:** Suitable for battery-powered applications.  
- **Open-Drain or Push-Pull Reset Output:** Configurable for different µP requirements.  
- **Adjustable Reset Threshold:** Some variants allow customization via external resistors.  

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