Description and Introduction

+3V Voltage Monitoring, Low-Cost, µP Supervisory Circuits The **MAX708TEUA** 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 the available knowledge:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Package:** 8-pin μMAX (TSSOP)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.6V, 2.5V, 3.0V, 3.3V, 5.0V)  
- **Reset Timeout Period:** 200ms (typical)  
- **Manual Reset Input:** Active-low (MR)  
- **Power-Fail Comparator:** Monitors an auxiliary voltage  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX708TEUA is designed to monitor power supply voltages in microprocessor systems, ensuring reliable operation by asserting a reset signal during power-up, power-down, or brownout conditions. It includes a manual reset input and a power-fail comparator for monitoring a secondary voltage.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures proper μP reset during undervoltage conditions.  
- **Manual Reset Capability:** Allows external pushbutton reset.  
- **Power-Fail Warning:** Early warning of impending power failure via PFI/PFO pins.  
- **Low Quiescent Current:** Typically 50μA.  
- **Space-Saving Package:** 8-pin μMAX for compact designs.  
- **Guaranteed Reset Valid Down to VCC = 1V.**
