Description and Introduction

+5V Microprocessor Supervisory Circuits The MAX818LCSA 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  
- **Part Number:** MAX818LCSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Type:** Voltage Monitor/Supervisory IC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-Set (1.575V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Quiescent Current:** 5μA (typ)  

### **Descriptions:**  
The MAX818LCSA monitors system voltage and provides a reset signal to the microprocessor when the supply voltage falls below a preset threshold. It ensures proper system operation by holding the μP in reset until the voltage stabilizes.  

### **Features:**  
- **Low Power Consumption:** 5μA typical supply current  
- **Precision Voltage Monitoring:** Guaranteed reset threshold accuracy (±1.5%)  
- **Manual Reset Input:** Allows external pushbutton reset  
- **Power-On Reset (POR) Circuitry:** Ensures valid reset at power-up  
- **Debounced Manual Reset Input:** Prevents false triggering  
- **No External Components Required:** Simplifies design  
- **Small Form Factor:** 8-pin SOIC package  

This information is based on Maxim Integrated's official datasheet for the MAX818LCSA.
