Description and Introduction

Microprocessor Supervisory Circuits The MAX802LESA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.6V, 2.32V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  
- **Low Quiescent Current:** 6μA (typical)  
- **Manual Reset Input:** Yes (active-low)  
- **Power-On Reset (POR) Circuitry:** Yes  

### **Descriptions:**  
The MAX802LESA monitors the power supply voltage of a microprocessor and provides a reset signal if the voltage drops below a preset threshold. It ensures reliable system operation by holding the microprocessor in reset until the supply voltage stabilizes.  

### **Features:**  
- Precision voltage monitoring  
- Adjustable or factory-set reset thresholds  
- Low power consumption  
- Guaranteed reset output valid down to VCC = 1V  
- Manual reset capability  
- No external components required for fixed threshold versions  
- Space-saving 8-pin SOIC package  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications where reliable power monitoring is critical.
