Description and Introduction

+5V, Low-Power, µP Supervisory Circuits with Adjustable Reset/Watchdog The MAX6303ESA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6303ESA+  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 8-SOIC (150mil)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (for 3.3V)  
- **Reset Timeout Period:** Adjustable (factory-set or external capacitor)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  
- **Manual Reset Input:** Yes (active-low)  
- **Watchdog Timer:** Yes (programmable)  
- **Power-Fail Comparator:** No  

### **Descriptions:**  
The MAX6303ESA+ is a low-power microprocessor supervisor designed to monitor system voltage and provide a reset signal to the μP during power-up, power-down, or brownout conditions. It includes an adjustable reset threshold, a watchdog timer, and a manual reset input for enhanced system reliability.  

### **Features:**  
- **Low Quiescent Current:** 5μA (typical) for power-sensitive applications.  
- **Adjustable Reset Threshold:** Allows customization for different supply voltages.  
- **Programmable Watchdog Timer:** Ensures system integrity by monitoring μP activity.  
- **Manual Reset Input:** Provides a user-initiated reset function.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Small Package:** 8-pin SOIC for space-constrained designs.  
- **High Accuracy:** ±1.5% reset threshold accuracy for reliable operation.  

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

Application Scenarios & Design Considerations

+5V, Low-Power, µP Supervisory Circuits with Adjustable Reset/Watchdog

Alternative Part Number

  • LTC2950-1CTS8 --: Push-button on/off controller with similar supervisory function and wide input range, suitable drop-in for many MAX6303 applications.
  • TPS3421EGDRYR --: Low-power push-button reset controller with adjustable delay, comparable supply monitoring and small package.
  • ADM6320CY29ARJZ --: Supervisory circuit with manual reset input and reset timeout, functionally similar to the MAX6303 supervisor family.
  • TPS3422EGDRYR --: Push-button reset controller with adjustable delay and low quiescent current, functionally comparable in reset/supervisory applications.
  • MIC2775-29YM5 --: Voltage supervisor with manual reset input and open-drain output, offers similar monitoring and reset behavior.
