Description and Introduction

Microprocessor Supervisory Circuits The MAX690AESA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX690AESA+  
- **Type:** Microprocessor Supervisory Circuit  
- **Package:** 8-SOIC (150 mils)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Voltage:** Adjustable or fixed (depending on variant)  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  

### **Descriptions:**
The MAX690AESA+ is designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal during power-up, power-down, or brownout conditions. It features low power consumption and comes in a compact SOIC package, making it suitable for battery-powered and space-constrained applications.

### **Features:**
- **Voltage Monitoring:** Ensures reliable μP reset during power failures.  
- **Low Power Consumption:** 6μA typical supply current.  
- **Wide Operating Voltage Range:** 1.2V to 5.5V.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Power-Fail Comparator:** Provides early warning for impending power loss.  
- **Guaranteed Reset Output:** Valid down to VCC = 1V.  
- **Small Footprint:** 8-pin SOIC package.  

This information is based solely on the manufacturer's datasheet and specifications.
