Description and Introduction

Low-Cost, uP Supervisory Circuits The **MAX707CUA** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-pin μMAX (UMAX)  
- **Type:** Microprocessor Supervisor/Monitor  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (e.g., 4.65V for 5V systems)  
- **Reset Timeout Period:** Typically 200ms (adjustable with external capacitor)  
- **Watchdog Timer:** Yes (1.6s nominal timeout)  
- **Manual Reset Input:** Yes (active-low)  
- **Power-On Reset (POR):** Yes  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX707CUA monitors system voltage levels 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 user-initiated resets.  

### **Features:**  
1. **Voltage Monitoring:** Ensures reliable μP operation by asserting reset when VCC falls below the threshold.  
2. **Watchdog Timer:** Resets the system if the watchdog input (WDI) is not toggled within the timeout period.  
3. **Manual Reset Capability:** Allows external pushbutton reset control.  
4. **Low Power Consumption:** Typically 50μA supply current.  
5. **Space-Saving Package:** 8-pin μMAX for compact designs.  
6. **Wide Voltage Range:** Supports 1.2V to 5.5V systems.  

For exact thresholds and timing, refer to the official **Maxim Integrated datasheet**.  

*(Note: Always verify with the latest datasheet, as specifications may vary by revision.)*
