Description and Introduction

Low-Cost, µP Supervisory Circuits The **MAX708CUA+T** is a microprocessor (µP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-pin µMAX  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 200ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 35µA (typical)  

### **Descriptions:**
- The MAX708CUA+T monitors µP power supplies, ensuring proper operation during power-up, power-down, and brownout conditions.  
- It provides a **reset signal** to the µP when the supply voltage drops below a preset threshold.  
- Includes both active-low (**RESET**) and active-high (**RESET**) outputs for flexibility.  

### **Features:**
1. **Power Supply Monitoring:** Detects voltage drops and generates a reset signal.  
2. **Manual Reset Input:** Allows for external µP reset via a pushbutton.  
3. **Low Power Consumption:** 35µA typical current draw.  
4. **Dual Reset Outputs:** Active-low and active-high reset signals.  
5. **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
6. **Small Form Factor:** 8-pin µMAX package for space-constrained applications.  

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

Application Scenarios & Design Considerations

Low-Cost, µP Supervisory Circuits

Alternative Part Number

  • ADM708AN --: Pin-compatible microprocessor supervisory circuit with reset output, same function and similar threshold, widely available from a different series.
  • TL7705ACP --: Classic 5V supply voltage supervisor with reset output, functionally equivalent for most MAX708 applications and from a distinct series.
  • MC34064P-5 --: Undervoltage sensing circuit providing reset for 5V systems, a feasible alternative with different naming and proven availability.
