Description and Introduction

3.0V or 3.3V microprocessor supervisory circuit. Reset threshold 3.075V. Active-high reset. Watchdog input. Backup-battery switch. Power-fail threshold accuracy +-2%. Power-fail comparator. Reset window +-2% The MAX804TEPA is a microprocessor reset circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Reset Threshold Options:** Available in multiple voltage options (e.g., 2.63V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 35µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX804TEPA is a precision voltage monitor designed to provide a reset signal to microprocessors or other digital systems when the power supply voltage drops below a preset threshold. It ensures proper system initialization during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Manual Reset Input:** Allows for external reset control via a pushbutton.  
- **Guaranteed Reset Output Valid Down to VCC = 1V**  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **No External Components Required:** Simplifies circuit design.  
- **Power-On Reset Generation:** Ensures reliable system startup.  
- **Available in Multiple Threshold Voltages:** Supports various system requirements.  

This information is sourced from Maxim Integrated's official datasheet for the MAX804TEPA.
