Description and Introduction

+5V, Low-Power uP Supervisory Circuits with Adjustable Reset/Watchdog The MAX6303CUA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated  

### **Part Number:**  
MAX6303CUA  

### **Description:**  
The MAX6303CUA is a low-power microprocessor supervisory circuit designed to monitor system power supplies and provide a reset signal to the μP in the event of a power failure or out-of-tolerance condition.  

### **Key Features:**  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Adjustable Reset Threshold:** Via external resistors (for custom voltage monitoring)  
- **Reset Timeout Period:** 140ms (min)  
- **Low Supply Current:** 8μA (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Manual Reset Input:** Allows external pushbutton reset control  
- **Power-Fail Comparator:** Provides early warning of power failure  
- **Package:** 8-pin μMAX (ultra-small outline package)  

### **Applications:**  
- Microprocessor (μP) and microcontroller (μC) systems  
- Embedded systems  
- Battery-powered devices  
- Industrial controls  
- Automotive electronics  

### **Package Type:**  
- **MAX6303CUA:** 8-pin μMAX

Description and Introduction

+5V, Low-Power uP Supervisory Circuits with Adjustable Reset/Watchdog The MAX6303CUA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 8-pin μMAX  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Adjustable or fixed (typically 140ms)  
- **Watchdog Timer:** Yes (programmable timeout)  
- **Manual Reset Input:** Yes  
- **Low Quiescent Current:** Typically 8μA  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX6303CUA monitors system voltage and provides a reset signal to the microprocessor when the supply voltage falls below a preset threshold. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.  

### **Features:**  
- **Voltage Monitoring:** Ensures reliable system operation by resetting the μP during power-up, power-down, and brownout conditions.  
- **Adjustable Reset Threshold:** Allows customization for different supply voltages.  
- **Watchdog Timer:** Prevents system lockup by resetting the μP if software fails to toggle the watchdog input.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Manual Reset Capability:** Provides a push-button reset option.  
- **Small Form Factor:** 8-pin μMAX package saves board space.
