Description and Introduction

+3V Voltage Monitoring, Low-Cost, レP Supervisory Circuits The **MAX708TESA** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Manufacturer:**  
- **MAXIM INTEGRATED** (now part of Analog Devices)  

### **Specifications:**  
- **Type:** Microprocessor (μP) Supervisor  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-set (e.g., 4.40V, 4.65V, etc.)  
- **Reset Timeout Period:** Adjustable or fixed (typically 200ms)  
- **Manual Reset Input:** Active-low (MR) for external reset control  
- **Power-Fail Comparator:** Monitors an auxiliary voltage (PFI/PFO)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The **MAX708TESA** ensures reliable system operation by monitoring power supply voltages and generating a reset signal if the voltage falls below a preset threshold.  
- It includes a **manual reset input (MR)** for user-initiated resets and a **power-fail comparator (PFI/PFO)** for early warning of power loss.  
- Designed for **5V, 3.3V, or lower-voltage systems**, it prevents erratic behavior in microprocessors during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures accurate reset triggering.  
- **Low Quiescent Current:** Typically 50μA (ideal for battery-powered systems).  
- **Power-Fail Warning:** PFI/PFO provides early power-loss indication.  
- **Manual Reset Capability:** External push-button reset support.  
- **Wide Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Industrial Temperature Range:** Operates from -40°C to +85°C.  

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

  • ADM708TARZ --: Pin-compatible supervisory circuit with the same reset threshold and active-low reset, direct functional drop-in replacement.
  • TL7705ACD --: Widely available voltage supervisor with comparable reset threshold and active-low reset output, suitable for most MAX708TESA applications.
  • MC33064D-5 --: Low-cost 5V supply supervisor with active-low reset, adequate substitute when exact threshold tolerance is not critical.
  • TL7705ACP --: Classic 5V supply supervisor with adjustable reset delay, commonly used as a substitute for MAX708-type supervisors in many designs.
  • MCP130T-450HI/TO --: Low-cost 5V voltage supervisor with active-low reset output, suitable for similar reset monitoring applications.
  • TL7705ACDR --: Widely available supply-voltage supervisor with comparable reset threshold and active-low reset output.
  • MC34064D-5G --: Low-cost 5V voltage supervisor offering similar reset functionality for microprocessor monitoring.
