Description and Introduction

3-Pin Microprocessor Reset Circuits The **MAX803ZEXR+** is a voltage monitor and reset IC manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-set (e.g., 4.63V, 4.38V, 3.08V, 2.93V, 2.63V, 2.32V, 1.88V, 1.60V)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5µA (typical)  
- **Output Type:** Active-low, push-pull  
- **Package:** SOT23-3  

### **Descriptions:**  
The MAX803ZEXR+ is a low-power microprocessor (µP) reset circuit that monitors system voltage and asserts a reset signal when the voltage drops below a preset threshold. It ensures proper system initialization during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable µP reset operation.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **No External Components Required:** Simplifies circuit design.  
- **Push-Pull RESET Output:** No external pull-up resistor needed.  
- **Small Form Factor:** Available in a compact SOT23-3 package.  

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