Description and Introduction

+3V Voltage Monitoring, Low-Cost, レP Supervisory Circuits The MAX706SMJA 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  
- **Type:** Microprocessor Supervisory Circuit  
- **Package:** 8-Pin CERDIP (SMJA)  
- **Operating Voltage Range:** 1.0V to 5.5V  
- **Reset Threshold Options:** Adjustable or Fixed (4.40V, 4.00V, 3.08V, 2.93V, 2.63V, 2.32V)  
- **Reset Timeout Period:** 200ms (min)  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Watchdog Timer:** 1.6s (typical)  
- **Manual Reset Input:** Yes (Active-Low)  
- **Power-On Reset (POR):** Yes  

### **Descriptions:**  
The MAX706SMJA is a supervisory circuit 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, manual reset input, and power-fail comparator for enhanced system reliability.  

### **Features:**  
- **Voltage Monitoring:** Monitors VCC for out-of-tolerance conditions.  
- **Reset Output:** Active-low RESET signal during power-up, power-down, or brownout conditions.  
- **Watchdog Timer:** Detects software lockups; resets the system if not toggled within 1.6s.  
- **Manual Reset Input:** Allows external pushbutton reset.  
- **Power-Fail Comparator:** Early warning for impending power failure.  
- **High Immunity to Voltage Transients:** Ensures reliable operation in noisy environments.  
- **Military Temperature Range:** Suitable for harsh environments.  

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

Application Scenarios & Design Considerations

+3V Voltage Monitoring, Low-Cost, レP Supervisory Circuits

Alternative Part Number

  • ADM706TANZ --: Pin-compatible microprocessor supervisory circuit with reset and watchdog functions, widely available and a direct functional drop-in for the MAX706 in most designs.
  • TPS3705-33D --: Integrated processor supervisor with reset and watchdog in a similar package, offering comparable threshold and timing behavior for supply monitoring applications.
  • CAT706VI-GT3 --: Low-cost supervisor IC with reset output and watchdog timer, functionally equivalent to the MAX706 family and suitable as a second-source alternative.
  • TPS3705-33DGNR --: Integrated supply voltage supervisor with reset and watchdog in a similar function class, suitable as a drop-in functional replacement.
  • MCP130-475DI/TO --: Voltage supervisor with active-low reset output, offering comparable supervisory functionality for many MAX706 applications.
