Description and Introduction

3.0V/3.3V Adjustable Microprocessor Supervisory Circuits The MAX794CSE+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX794CSE+  
- **Package:** 16-SOIC (150 mil)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Voltage Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Adjustable (200ms min)  
- **Watchdog Timer Timeout:** 1.6s (typical)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Quiescent Current:** 40μA (typical)  

### **Descriptions:**
- The MAX794CSE+ monitors power supply voltages for microprocessors and digital systems.  
- It provides a reset signal during power-up, power-down, or brownout conditions.  
- Includes a watchdog timer to detect software lockups.  
- Features manual reset input and battery backup switchover for CMOS RAM.  

### **Features:**
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
- **Adjustable Reset Threshold:** Can be set via external resistors.  
- **Watchdog Timer:** Ensures system integrity by resetting the μP if software fails to respond.  
- **Manual Reset Input:** Allows external pushbutton reset.  
- **Battery Backup Support:** Switches to backup battery when VCC fails.  
- **Low Power Consumption:** Ideal for battery-powered applications.  

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