Description and Introduction

Microprocessor Supervisory Circuits The MAX805LCPA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX805LCPA  
- **Package:** 8-pin PDIP (Plastic Dual In-Line Package)  
- **Type:** Microprocessor Voltage Monitor/Supervisory Circuit  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Typically 140ms (min)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial grade)  
- **Quiescent Current:** Low (typically a few microamps)  
- **Output Type:** Active-low reset output (RESET)  

### **Descriptions:**  
The MAX805LCPA is designed to monitor system voltage levels in microprocessor-based applications. It ensures proper system operation by asserting a reset signal when the supply voltage falls below a specified threshold, preventing erratic behavior during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Power-On Reset (POR):** Guarantees a valid reset signal during power-up.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Fixed or Adjustable Threshold:** Some variants offer adjustable reset thresholds via external resistors.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Compact Package:** 8-pin PDIP for easy integration.  

This information is strictly based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official MAX805LCPA datasheet.

Application Scenarios & Design Considerations

Microprocessor Supervisory Circuits

Alternative Part Number

  • ADM805LAN --: Pin-compatible microprocessor supervisory circuit with reset and watchdog functions, direct functional equivalent from the same product family lineage.
  • DS1232 --: Classic microprocessor supervisor IC offering reset and watchdog timing, widely used as a drop-in functional substitute in similar applications.
  • TL7705ACP --: Low-cost supply voltage supervisor with reset output, suitable functional replacement when watchdog timing is not strictly required.
