Description and Introduction

+5V, Low-Power uP Supervisory Circuits with Adjustable Reset/Watchdog The MAX6303EPA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6303EPA  
- **Package:** 8-pin PDIP (Plastic Dual Inline Package)  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (200ms typical)  
- **Watchdog Timer:** Yes (1.6s typical timeout)  
- **Manual Reset Input:** Yes (active-low MR pin)  
- **Power-On Reset (POR):** Yes  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX6303EPA is designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal when the supply voltage drops below a preset threshold. It includes a watchdog timer to detect software lockups and a manual reset input for external control.  

### **Features:**  
- Low quiescent current (10μA typical)  
- Precision voltage monitoring  
- Adjustable or fixed reset threshold  
- Watchdog timer with 1.6s default timeout  
- Manual reset capability  
- Guaranteed reset output valid down to VCC = 1V  
- Small 8-pin PDIP package  

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