Description and Introduction

3.0V/3.3V Microprocessor Supervisory Circuits The MAX690SCSA+ is a microprocessor (µP) supervisory circuit manufactured by Maxim Integrated. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX690SCSA+  
- **Type:** µP Supervisory Circuit  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (for 5V supply)  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 35µA (typical)  

### **Descriptions:**
The MAX690SCSA+ is designed to monitor power supply voltages in µP and digital systems. It ensures proper system operation by generating a reset signal when the supply voltage drops below a preset threshold. It also includes a watchdog timer and manual reset input for enhanced system reliability.

### **Features:**
- **Precision Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Watchdog Timer:** Detects µP activity and resets if stalled.  
- **Low Power Consumption:** 35µA typical supply current.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V.  
- **200ms Reset Pulse Width:** Ensures proper µP initialization.  
- **Space-Saving Package:** 8-pin SOIC for compact designs.  

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