Description and Introduction

µP Supervisory Circuits The MAX707CUA-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-pin μMAX  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 35μA (typ)  

### **Descriptions:**
- The MAX707CUA-T 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.  
- The device includes a watchdog timer to detect software lockups.  

### **Features:**
- **Manual Reset Input:** Allows for external pushbutton reset control.  
- **Watchdog Timer:** 1.6s timeout (typ) to monitor system activity.  
- **Power-Fail Comparator:** Provides early warning of power failure.  
- **Low-Power Operation:** Suitable for battery-powered applications.  
- **Guaranteed Reset Output Valid Down to VCC = 1V.**  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

µP Supervisory Circuits

Alternative Part Number

  • ADM707ARZ --: Pin-compatible microprocessor supervisor with reset and watchdog functions, widely available and a direct functional equivalent.
  • 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 providing reset for 5V systems, suitable alternative when full watchdog features are not required.
  • MC33064D-5G --: Undervoltage sensing circuit in SOIC package from the same manufacturer, suitable for reset/supervisory applications with similar supply monitoring behavior.
