Reset window +-2% The MAX802SCPA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-Set (e.g., 2.63V, 2.93V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Quiescent Current:** 5μA (typical)  

### **Descriptions:**
- Monitors power supply voltage for microprocessors and digital systems.  
- Provides a reset signal to the μP when voltage drops below a preset threshold.  
- Ensures proper system initialization during power-up, power-down, or brownout conditions.  

### **Features:**
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation.  
- **No External Components Required:** Simplifies circuit design.  
- **Power-Fail Comparator:** Provides early warning for impending power failure.
