Description and Introduction

+3V Voltage Monitoring, Low-Cost, µP Supervisory Circuits The MAX708R is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual details about the device:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Manual Reset Input:** Active-low (MR)  
- **Power-Fail Comparator:** Yes (PFI/PFO)  
- **Watchdog Timer:** 1.6s (typ) timeout  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**
The MAX708R monitors power supply voltages and provides reset signals to microprocessors during power-up, power-down, or brownout conditions. It includes a watchdog timer, manual reset input, and a power-fail comparator for early warning of power loss.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable μP reset.  
- **Adjustable or Fixed Reset Threshold:** Supports multiple voltage levels.  
- **Watchdog Timer:** Prevents system lock-up.  
- **Manual Reset Input:** Allows user-initiated reset.  
- **Power-Fail Comparator:** Monitors an auxiliary power supply.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Wide Operating Voltage Range:** Compatible with 1.2V to 5.5V systems.  

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