Description and Introduction

+5V Microprocessor Supervisory Circuits The MAX819LCSA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX819LCSA+  
- **Package:** 8-pin SOIC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Adjustable or fixed (typically 140ms)  
- **Watchdog Timer:** Yes (programmable timeout)  
- **Manual Reset Input:** Yes (active-low)  
- **Power-On Reset (POR) Circuitry:** Yes  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
The MAX819LCSA+ monitors system voltage and provides a reset signal to the microprocessor when the supply voltage falls below a preset threshold. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.  

### **Features:**  
- Low supply current (typically 10μA)  
- Precision voltage monitoring  
- Adjustable or fixed reset threshold options  
- Watchdog timer with programmable timeout  
- Manual reset capability  
- Guaranteed reset output valid down to VCC = 1V  
- Space-saving 8-pin SOIC package  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications to ensure reliable system operation.
