Description and Introduction

Microprocessor Supervisory Circuits The MAX690AESA+T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
Maxim Integrated  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** 200ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-SOIC (150mil)  

### **Descriptions:**  
- Monitors microprocessor power supply voltage to prevent system errors during power-up, power-down, or brownout conditions.  
- Provides a reset signal to the μP when the supply voltage drops below a preset threshold.  
- Includes a manual reset input for external system reset control.  
- Low power consumption, making it suitable for battery-powered applications.  

### **Features:**  
- Precision voltage monitoring for 3V, 3.3V, and 5V systems.  
- Guaranteed reset output valid down to VCC = 1V.  
- 200ms (minimum) reset timeout period.  
- Manual reset input for external control.  
- Low quiescent current (35μA typical).  
- No external components required.  
- Space-saving 8-pin SOIC package.  

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

Application Scenarios & Design Considerations

Microprocessor Supervisory Circuits

Alternative Part Number

  • ADM690AARNZ --: Pin-compatible microprocessor supervisory circuit with reset and watchdog functions, direct functional equivalent to the MAX690A in an 8-pin SOIC package.
  • DS1232LPS-2 --: Microprocessor supervisor with reset and watchdog timing, similar supervisory functionality and widely used as a drop-in style replacement in monitoring circuits.
  • TPS3705-33DGNR --: Supply voltage supervisor with reset output and watchdog, offers comparable monitoring behavior for 3.3V/5V systems as an alternative supervisory IC.
