Description and Introduction

Low-Cost, µP Supervisory Circuits The MAX708CSA+T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX708CSA+T  
- **Package:** 8-SOIC (150 mil)  
- **Type:** μP Supervisory Circuit  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.6V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Manual Reset Input:** Yes (active-low)  
- **Watchdog Timer:** Yes (1.6s typical timeout)  
- **Power-Fail Comparator:** Yes  

### **Descriptions:**  
The MAX708CSA+T is a precision voltage monitor designed to ensure proper operation of microprocessors and digital systems. It provides reset signals during power-up, power-down, and brownout conditions. The watchdog timer monitors system activity, while the power-fail comparator provides early warning of impending power failure.  

### **Features:**  
- **Reset Output:** Active-low or active-high (user-selectable)  
- **Watchdog Timer:** Monitors μP activity; resets if no transition detected within timeout period  
- **Manual Reset Input:** Allows external pushbutton reset  
- **Power-Fail Comparator:** Early warning for power loss  
- **Low Quiescent Current:** Typically 50μA  
- **Adjustable or Fixed Reset Thresholds:** Multiple options available  
- **Space-Saving 8-Pin SOIC Package**  

This information is strictly based on the manufacturer's datasheet and technical specifications.

Application Scenarios & Design Considerations

Low-Cost, µP Supervisory Circuits

Alternative Part Number

  • ADM708ARZ --: Pin-compatible microprocessor supervisory circuit with reset and watchdog functions, direct functional equivalent to the MAX708 in an SOIC package.
  • TL7705ACD --: Widely available supply-voltage supervisor with adjustable reset threshold and reset output, suitable replacement for basic reset monitoring functions.
  • MC33064D-5 --: Undervoltage sensing circuit with 5V threshold and open-collector reset output, a cost-effective alternative for simple reset supervision.
  • TL7705ACP --: Classic 5V supply voltage supervisor with reset output, similar function and commonly used as a replacement in supervisory circuits.
  • MC33064P-5 --: Undervoltage sensing circuit with reset output for 5V systems, suitable alternative when full watchdog features are not required.
