Description and Introduction

3.0V/3.3V Adjustable Microprocessor Supervisory Circuits The MAX794ESE is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX794ESE  
- **Package:** 16-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Adjustable (200ms typical for fixed threshold)  
- **Watchdog Timer:** 1.6s nominal timeout  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The MAX794ESE monitors power supply voltages to ensure proper μP operation.  
- It provides a reset signal to the μP when the supply voltage drops below a preset threshold.  
- Includes a watchdog timer to detect software lockups.  
- Features manual reset input for external system control.  

### **Features:**
- **Power Supply Monitoring:** Resets μP during power-up, power-down, and brownout conditions.  
- **Adjustable or Fixed Threshold:** Supports factory-set or user-defined reset thresholds.  
- **Watchdog Timer:** Monitors μP activity; resets system if not toggled within timeout period.  
- **Manual Reset Input:** Allows external push-button reset.  
- **Low Quiescent Current:** Typically 50μA for power efficiency.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  

This device is commonly used in embedded systems, industrial controls, and automotive electronics for reliable power management.
