Description and Introduction

+3V Voltage Monitoring, Low-Cost, µP Supervisory Circuits The MAX708SCSA-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. It is designed to monitor the power supply in μP and digital systems, ensuring proper operation during power-up, power-down, and brownout conditions.  

### **Key Features:**  
- **Supply Voltage Monitoring:** Monitors +5V, +3.3V, or +3V power supplies.  
- **Reset Output:** Active-low RESET signal asserts when VCC falls below the reset threshold.  
- **Manual Reset Input:** Allows for external pushbutton reset control.  
- **Power-Fail Comparator:** Provides early warning for impending power failure.  
- **Reset Threshold Accuracy:** ±1.5% for precise monitoring.  
- **Reset Timeout Period:** 200ms (min) to ensure proper μP initialization.  
- **Low Quiescent Current:** 35μA (typ) for power efficiency.  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit).  

### **Applications:**  
- Microprocessor and microcontroller systems  
- Embedded controllers  
- Industrial controls  
- Critical power monitoring  

The MAX708SCSA-T ensures reliable system operation by preventing data corruption during unstable power conditions.

Description and Introduction

+3V Voltage Monitoring, Low-Cost, µP Supervisory Circuits The MAX708SCSA-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** 2.63V, 2.93V, 3.08V, 4.38V, 4.63V (factory-set)  
- **Reset Timeout Period:** 200ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Manual Reset Input:** Active-low (MR) for external reset control  
- **Power-On Reset (POR) Generator:** Ensures proper system initialization  
- **Watchdog Timer:** 1.6s timeout (default), resettable via WDI input  

### **Descriptions:**  
The MAX708SCSA-T monitors power supply voltages and provides a reset signal to the microprocessor during power-up, power-down, or brownout conditions. It includes a watchdog timer to detect software lockups and a manual reset input for external control.  

### **Features:**  
- **Low Power Consumption:** 50μA (typical)  
- **Precision Voltage Monitoring:** Ensures reliable reset thresholds  
- **Watchdog Timer:** Prevents system crashes due to code execution errors  
- **Manual Reset Capability:** Allows user-initiated reset via MR pin  
- **Guaranteed Reset Assertion Down to VCC = 1V**  
- **Space-Saving 8-Pin SOIC Package**  

This device is commonly used in embedded systems, industrial controls, and automotive applications where reliable power monitoring is critical.
