Description and Introduction

+3V Voltage Monitoring, Low-Cost, µP Supervisory Circuits The **MAX708RCUA+** is a microprocessor (µP) supervisory circuit manufactured by **Maxim Integrated**.  

### **Specifications:**  
- **Supply Voltage (VCC):** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 200ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (UCSP)  
- **Manual Reset Input:** Active-low (MR)  
- **Watchdog Timer:** 1.6s timeout (typical)  

### **Descriptions:**  
- Monitors µP power supply and generates a reset signal if voltage drops below a preset threshold.  
- Includes a watchdog timer to detect µP lockup.  
- Provides manual reset capability via the **MR** pin.  
- Low quiescent current (35µA typical).  

### **Features:**  
- Precision voltage monitoring  
- Adjustable or factory-set reset thresholds  
- Power-fail comparator for early warning  
- Guaranteed reset output valid down to **VCC = 1V**  
- No external components required for fixed threshold versions  

This device ensures reliable system operation by preventing µP malfunctions during power-up, power-down, or brownout conditions.
