Description and Introduction

+3V Voltage Monitoring, Low-Cost, µP Supervisory Circuits The **MAX708TCSA+** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:  

### **Manufacturer:**  
- **MAXIM (Maxim Integrated)**  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.575V, 2.32V, 2.93V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 200ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-pin SOIC (TCSA+)  
- **Manual Reset Input:** Yes (active-low)  
- **Watchdog Timer:** Yes (1.6s typical timeout)  
- **Power-On Reset (POR) Circuit:** Yes  

### **Descriptions:**  
- The **MAX708TCSA+** monitors power supply voltages for microprocessors and digital systems.  
- It provides a **reset signal** to the μP during power-up, power-down, or brownout conditions.  
- Includes a **watchdog timer** to detect software lockups.  
- Features a **manual reset input** for user-initiated resets.  

### **Features:**  
- **Precision Voltage Monitoring** for reliable system reset.  
- **Low Quiescent Current:** 35μA (typical).  
- **Adjustable or Fixed Reset Thresholds** for flexibility.  
- **Guaranteed Reset Assertion Down to VCC = 1V.**  
- **Watchdog Timer** with 1.6s timeout.  
- **Manual Reset Input** for external system control.  

This IC is commonly used in **embedded systems, industrial controls, and automotive electronics** for reliable power management.  

(Note: For detailed electrical characteristics, refer to the official **MAX708 datasheet** from Maxim/Analog Devices.)

Application Scenarios & Design Considerations

+3V Voltage Monitoring, Low-Cost, µP Supervisory Circuits

Alternative Part Number

  • TL7705ACD --: Single-supply supervisor with active-low reset and manual reset input, functionally similar to the MAX708 in an SOIC-8 package.
  • MC34064D-5 --: Voltage supervisor with reset output, widely available and commonly used as a MAX708 substitute in 5V systems.
  • ADM708TARZ --: Direct functional equivalent of the MAX708 supervisor family with reset and watchdog features in SOIC-8.
  • TL7705ACDR --: Widely available voltage supervisor with adjustable threshold and active-low reset, suitable functional replacement for 5V monitoring.
  • MC33064D-5G --: Low-cost 5V undervoltage sensing circuit with open-collector reset output, usable as a drop-in functional substitute.
