Description and Introduction

3.0V/3.3V Adjustable Microprocessor Supervisory Circuits The MAX793SESE+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX793SESE+  
- **Package:** 16-SOIC (150 mils)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (over temperature)  
- **Reset Timeout Period:** Adjustable (200ms min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Watchdog Timer:** Programmable (1.6s nominal timeout)  
- **Manual Reset Input:** Yes (active-low)  
- **Power-On Reset (POR):** Yes  
- **Battery Backup Input:** Yes (for CMOS RAM backup)  
- **Quiescent Current:** 40μA (typical)  

### **Descriptions:**
The MAX793SESE+ is a microprocessor supervisory circuit designed to monitor power supply voltages and provide reset signals to μPs during power-up, power-down, and brownout conditions. It includes a watchdog timer, manual reset input, and battery backup switch for CMOS RAM.  

### **Features:**
1. **Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
2. **Adjustable Reset Timeout:** User-selectable reset delay.  
3. **Watchdog Timer:** Ensures system integrity by resetting the μP if software fails.  
4. **Manual Reset Input:** Allows external pushbutton reset.  
5. **Battery Backup Switching:** Automatically switches to backup battery when VCC fails.  
6. **Low Power Consumption:** Ideal for battery-powered applications.  
7. **High Accuracy Reset Threshold:** Ensures reliable system operation.  

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