Description and Introduction

+5V, Low-Power uP Supervisory Circuits with Adjustable Reset/Watchdog The MAX6303CSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6303CSA  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.575V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  

### **Descriptions:**
The MAX6303CSA monitors microprocessor power supplies to ensure proper system operation. It generates a reset signal when the supply voltage drops below a preset threshold, preventing erratic behavior during power-up, power-down, or brownout conditions. It is suitable for low-voltage and battery-powered applications.

### **Features:**
- **Low Power Consumption:** 5μA typical supply current  
- **Adjustable or Fixed Reset Thresholds:** Multiple options available  
- **Manual Reset Input:** Allows external reset control  
- **Power-On Reset (POR) Circuitry:** Ensures proper startup  
- **140ms Minimum Reset Timeout:** Guarantees stable operation  
- **Wide Operating Voltage Range:** 1.6V to 5.5V  
- **Small Footprint:** 8-pin SOIC package  

This information is based solely on the manufacturer's datasheet.

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6303CSA  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.6V, 2.2V, 2.7V, 3.0V, 3.3V, 5.0V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Supply Current:** 5μA (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Manual Reset Input:** Yes (active-low)  
- **Watchdog Timer:** Yes (1.6s timeout)  
- **Output Type:** Active-low, push-pull  

### **Descriptions:**  
The MAX6303CSA is a low-power μP supervisory circuit designed to monitor system voltages and provide a reset signal to the microprocessor during power-up, power-down, or brownout conditions. It includes an adjustable or fixed reset threshold, a watchdog timer, and a manual reset input.  

### **Features:**  
- **Low Quiescent Current:** 5μA (typ)  
- **Adjustable or Fixed Reset Threshold**  
- **Watchdog Timer with 1.6s Timeout**  
- **Manual Reset Input**  
- **Guaranteed Reset Valid Down to VCC = 1V**  
- **No External Components Required for Fixed Threshold Versions**  
- **Space-Saving 8-Pin SOIC Package**  

This information is strictly based on the manufacturer's datasheet and technical documentation.
