Description and Introduction

3-Pin Microprocessor Reset Circuits The MAX803SEXR is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Type:** Voltage Monitor/Supervisory Circuit  
- **Output Type:** Active-Low, Push-Pull Reset  
- **Reset Threshold Options:** Multiple (e.g., 2.63V, 2.93V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5μA (typical)  
- **Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-3  

### **Descriptions:**  
- The MAX803SEXR monitors system voltage and provides a reset signal to the μP when the voltage falls below a preset threshold.  
- It ensures proper system initialization during power-up, power-down, or brownout conditions.  
- The device features a manual reset input (if applicable in the variant).  

### **Features:**  
- **Low Power Consumption:** 5μA typical supply current.  
- **Precision Voltage Monitoring:** Guaranteed reset threshold accuracy (±1.5%).  
- **No External Components Required:** Simplifies design.  
- **Push-Pull RESET Output:** Eliminates the need for a pull-up resistor.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Small Form Factor:** Available in a compact SOT23-3 package.  

For exact threshold voltage options and additional details, refer to the official datasheet from Maxim Integrated/Analog Devices.
