Description and Introduction

Low-Cost, uP Supervisory Circuits The MAX707CPA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX707CPA  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** 4.40V, 4.65V, or user-adjustable  
- **Reset Timeout Period:** 200ms (min)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Manual Reset Input:** Active-low (MR)  
- **Watchdog Timer:** 1.6s timeout (typical)  

### **Descriptions:**
- The MAX707CPA monitors power supply voltages for μP and digital systems.  
- It provides a reset signal to the μP when the supply voltage drops below a preset threshold.  
- Includes a watchdog timer to detect software malfunctions.  
- Features a manual reset input for external system control.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Typically 50μA supply current.  
- **Watchdog Timer:** Resets the system if software fails to toggle within the timeout period.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures proper reset assertion.  
- **No External Components Required:** Simplifies design.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official documentation.

Application Scenarios & Design Considerations

Low-Cost, uP Supervisory Circuits

Alternative Part Number

  • ADM707AN --: Pin-compatible microprocessor supervisory circuit with reset and watchdog functions, direct functional equivalent to the MAX707 in an 8-pin DIP package.
  • ICL707CPD --: Same 707-series supervisory function with active-high/low reset and watchdog timer, widely used as a drop-in replacement in 8-pin DIP.
  • TL7705ACP --: General-purpose supply voltage supervisor with reset output, suitable functional substitute when exact pinout match is not mandatory.
  • MC33064P-5 --: Undervoltage sensing circuit providing reset signal, commonly used as a lower-cost alternative for supply monitoring in 8-pin DIP packages.
