Description and Introduction

Microprocessor supervisory circuit. Reset threshold 2.85V to 3.00V. Active-low reset.Active-high reset.Low-line early warning output.Backup-battery switchover.External switch driver.Power-fail comparator.Battery OK output.Watchdog input.Ma The MAX793SESE is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Package:** 16-pin narrow SOIC (SESE)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Adjustable or fixed (typically 200ms)  
- **Watchdog Timer:** Includes a programmable watchdog timer with a timeout range of 15ms to 1.6s  
- **Manual Reset Input:** Supports pushbutton reset  
- **Power-Fail Comparator:** Monitors an auxiliary voltage for early warning of power failure  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX793SESE is a comprehensive μP supervisory circuit designed to monitor power supply voltages, provide reset signals, and ensure proper system operation. It integrates a watchdog timer, manual reset input, and power-fail comparator for enhanced system reliability.  

### **Features:**
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions and asserts reset when necessary.  
- **Adjustable Reset Threshold:** Allows customization for different voltage levels.  
- **Watchdog Timer:** Ensures system integrity by triggering a reset if the μP fails to respond.  
- **Manual Reset Input:** Supports external pushbutton reset functionality.  
- **Power-Fail Comparator:** Provides early warning for impending power loss.  
- **Low Quiescent Current:** Optimized for power-sensitive applications.  
- **Wide Operating Voltage Range:** Suitable for 3.3V and 5V systems.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
