Description and Introduction

Low-Cost, µP Supervisory Circuits The MAX707 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  
- **Reset Threshold Options:**  
  - 4.65V (MAX707)  
  - 4.40V (MAX708)  
  - 3.08V (MAX709)  
  - Adjustable (MAX705/MAX706)  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 8-pin DIP, SO, μMAX  

### **Descriptions:**
The MAX707 monitors the power supply voltage of a microprocessor and provides a reset signal if the voltage drops below a specified threshold. It ensures proper system initialization and prevents data corruption during power-up, power-down, or brownout conditions.  

### **Features:**
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Power-On Reset (POR) Generation:** Ensures a valid reset signal during power-up.  
- **Low Quiescent Current:** Typically 50μA, reducing power consumption.  
- **Watchdog Timer (MAX705/MAX706 variants):** Monitors software execution and resets the system if it fails to toggle within a set time.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **Space-Saving Packages:** Available in 8-pin DIP, SO, and μMAX packages.  

The MAX707 is commonly used in embedded systems, industrial controls, and battery-powered applications for reliable power monitoring and reset functionality.
