Description and Introduction

Microprocessor Supervisory Circuits The MAX691MJE is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 10μA (typical)  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** Adjustable (default 200ms)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin DIP, SO  

### **Descriptions:**
- The MAX691MJE monitors microprocessor power supplies and ensures proper system operation during power-up, power-down, and brownout conditions.  
- It provides a reset signal to the μP if the supply voltage drops below a preset threshold, preventing erratic behavior.  
- Includes watchdog timer and manual reset functionality for enhanced system reliability.  

### **Features:**
- **Low Power Consumption:** 10μA typical supply current.  
- **Precision Voltage Monitoring:** Accurate reset threshold for reliable operation.  
- **Watchdog Timer:** Detects μP code execution failures.  
- **Manual Reset Input:** Allows external reset control.  
- **Battery Backup Switching:** Supports automatic switchover to backup power.  
- **Wide Operating Voltage Range:** Compatible with 1.2V to 5.5V systems.
