Description and Introduction

Low-Cost, uP Supervisory Circuits The MAX708MJA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Package:** 8-pin CERDIP (MJA package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (e.g., 4.65V, 4.40V, 3.08V, etc.)  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** -55°C to +125°C (military-grade)  
- **Manual Reset Input:** Active-low (MR) with debounce  
- **Watchdog Timer:** 1.6s timeout (typical)  

### **Descriptions:**  
The MAX708MJA is a precision voltage monitor designed to ensure proper system operation in μP and digital systems. It provides reset signals during power-up, power-down, and brownout conditions. The watchdog timer monitors μP activity, and the manual reset input allows for external system reset control.  

### **Features:**  
- **Reset Output:** Active-low or active-high (depending on variant)  
- **Power-On Reset (POR) Generation:** Ensures proper startup  
- **Watchdog Timer:** Monitors μP activity; resets if no trigger within timeout  
- **Manual Reset Input:** Allows external system reset  
- **Low Power Consumption:** Typically 50μA  
- **High Noise Immunity:** Glitch-free reset operation  
- **Military Temperature Range:** Suitable for harsh environments
