Description and Introduction

35 mA, 2.0 V to 5.5 V, low-voltage, high-accuracy, quad voltage monitor The MAX6709EUB is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX6709EUB  
- **Package:** 10-pin µMAX (µSOP)  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Reset Threshold Options:** Factory-set (multiple options available)  
- **Reset Timeout Period:** Adjustable or fixed (depends on variant)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Typically 6µA (low power consumption)  
- **Output Type:** Active-low reset (open-drain or push-pull, depending on variant)  

### **Descriptions:**
The MAX6709EUB is a low-power μP supervisory circuit designed to monitor system voltages and provide a reset signal to the processor when the supply voltage falls below a preset threshold. It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**
1. **Wide Voltage Range:** Operates from 1.6V to 5.5V, making it suitable for various low-voltage systems.  
2. **Low Quiescent Current:** Consumes only 6µA (typical), ideal for battery-powered applications.  
3. **Precision Voltage Monitoring:** Factory-trimmed reset thresholds ensure accuracy.  
4. **Manual Reset Input:** Allows external pushbutton reset capability.  
5. **Adjustable or Fixed Reset Timeout:** Some variants offer flexibility in reset pulse width.  
6. **Small Package:** 10-pin µMAX (µSOP) footprint saves board space.  
7. **Open-Drain or Push-Pull Output:** Selectable output configuration for compatibility with different systems.  
8. **Power-Fail Comparator:** Optional feature in some variants for early warning of power loss.  

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

Application Scenarios & Design Considerations

35 mA, 2.0 V to 5.5 V, low-voltage, high-accuracy, quad voltage monitor

Alternative Part Number

  • ADM6710JARJZ --: Multi-voltage supervisor with similar functionality and pin-compatible footprint, from the former Maxim product line now under ADI.
  • TPS3705-33DGNR --: Triple-supply voltage supervisor offering comparable monitoring channels and reset outputs in a small package.
  • LTC2935CTS8-1 --: Compact multi-supply supervisor with adjustable thresholds, suitable as a functional substitute for system monitoring.
  • TPS3700DDCR --: Dual-voltage supervisor with adjustable thresholds and open-drain reset, functionally comparable to the MAX6709 family.
  • CAT811TTBI-GT3 --: Single-voltage supervisor with manual reset and active-low reset output, suitable as a lower-cost functional substitute where only one rail needs monitoring.
  • ADM6711TAKSZ-REEL7 --: Pin-compatible microprocessor supervisor in a similar 10-pin package with comparable reset threshold and open-drain output, widely available from ADI.
  • MCP1316MTB29E/TO --: Voltage supervisor with reset output in a small package, suitable as a functional substitute when exact pinout match is not critical.
