Description and Introduction

Full-Featured µP Supervisory Circuit with ±1.5% Reset Accuracy The MAX807NEWE+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 3-SOT-23  
- **Operating Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (varies by variant)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some variants)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** Active-low reset output (RESET)  
- **Quiescent Current:** Low (typically a few μA)  

### **Descriptions:**  
The MAX807NEWE+ is a low-power microprocessor supervisory circuit designed to monitor system voltage and provide a reset signal to the μP during power-up, power-down, or brownout conditions. It ensures reliable system operation by holding the μP in reset until the supply voltage stabilizes.  

### **Features:**  
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
- **Manual Reset Input:** Some variants include a manual reset (MR) pin for external reset control.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Small Form Factor:** Available in a compact 3-pin SOT-23 package.  
- **Wide Operating Voltage Range:** Supports 1.8V to 5.5V systems.  
- **Guaranteed Reset Output:** Ensures valid reset signal down to VCC = 1V.  

For exact threshold voltages and variant-specific details, refer to the official datasheet from Analog Devices (formerly Maxim Integrated).
