Description and Introduction

Low-Cost / uP Supervisory Circuits The MAX813LCSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX813LCSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Voltage Options:** Adjustable or fixed (e.g., 4.65V for 5V systems)  
- **Reset Timeout Period:** 140ms (typical)  
- **Watchdog Timer Timeout:** 1.6s (typical)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial grade)  
- **Manual Reset Input:** Active-low (MR)  
- **Power-On Reset (POR) Circuit:** Ensures proper system initialization  
- **Low Quiescent Current:** 50μA (typical)  

### **Descriptions:**
The MAX813LCSA is a supervisory IC designed to monitor power supply voltages and provide a reset signal to microprocessors or microcontrollers in case of power failures or unstable conditions. It integrates a watchdog timer, manual reset input, and power-fail comparator for robust system monitoring.

### **Features:**
- **Power Supply Monitoring:** Automatically asserts reset when VCC drops below a threshold.  
- **Watchdog Timer:** Resets the system if the watchdog input is not toggled within the set timeout.  
- **Manual Reset Input:** Allows external push-button reset functionality.  
- **Power-Fail Comparator:** Early warning for impending power failure.  
- **Low-Power Operation:** Suitable for battery-powered applications.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  

The MAX813LCSA is commonly used in embedded systems, industrial controls, and automotive electronics where reliable power monitoring is critical.

Application Scenarios & Design Considerations

Low-Cost / uP Supervisory Circuits

Alternative Part Number

  • ADM813LARZ --: Pin-compatible microprocessor supervisory circuit with reset and watchdog functions, direct functional equivalent to the MAX813L.
  • TPS3808G01DBVR --: Adjustable supervisory circuit with manual reset and watchdog, covers the same monitoring role in a small SOT-23 package.
  • CAT823STDI-GT3 --: Low-cost supervisor with reset and watchdog timer, suitable drop-in replacement for supply monitoring applications.
  • TL7705ACD --: Widely available supply voltage supervisor with adjustable reset delay, functionally similar reset/watchdog role in 8-pin SOIC.
  • MC33064D-5 --: Undervoltage sensing circuit providing reset output for 5V systems, low-cost alternative in SOIC package.
  • CAT813LVI-GT3 --: Direct functional equivalent of the MAX813L supervisor family with reset and watchdog, available in SOIC-8, good second-source option.
