Description and Introduction

±1% Accuracy, Low-Power, +3V and +5V µP Supervisory Circuits The MAX814LCSA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX814LCSA+  
- **Package:** 8-SOIC (Small Outline Integrated Circuit)  
- **Type:** Microprocessor Supervisor  
- **Voltage - Threshold:** 4.65V  
- **Number of Voltages Monitored:** 1  
- **Reset Timeout:** 140ms (Minimum)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Output Type:** Active-Low, Push-Pull  
- **Supply Voltage (Vcc):** 1.2V to 5.5V  
- **Manual Reset Input:** Yes  
- **Watchdog Timer:** Yes (1.6s typical timeout)  

### **Descriptions:**  
The MAX814LCSA+ is a precision voltage monitor designed to ensure proper system operation in microprocessor-based applications. It monitors the power supply voltage and provides a reset signal to the μP if the voltage drops below a preset threshold. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Watchdog Timer:** Detects system lockups with a 1.6s timeout.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Low Power Consumption:** Typically 50μA supply current.  
- **Push-Pull Reset Output:** No external pull-up resistor required.  
- **Wide Operating Voltage Range:** 1.2V to 5.5V.  
- **140ms Minimum Reset Pulse Width:** Ensures proper system initialization.  

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