Description and Introduction

+5V Microprocessor Supervisory Circuits The MAX819MCSA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX819MCSA+  
- **Type:** Microprocessor Supervisory Circuit  
- **Package:** 8-Pin SOIC  
- **Operating Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Options:** Adjustable or Fixed (1.6V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Manual Reset Input:** Yes (Active-Low)  
- **Watchdog Timer:** Yes (1.6s timeout)  
- **Power-On Reset (POR):** Yes  

### **Descriptions:**
The MAX819MCSA+ monitors system voltage levels and provides a reset signal to the microprocessor when the voltage falls below a preset threshold. It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions. The device includes a watchdog timer to detect software hangs and a manual reset input for user-initiated resets.

### **Features:**
- **Low Power Consumption:** 35μA (typ) supply current  
- **Adjustable or Fixed Reset Threshold:** Multiple options available  
- **Watchdog Timer:** Monitors software execution  
- **Manual Reset Input:** Allows external reset triggering  
- **Guaranteed Reset Valid Down to VCC = 1V**  
- **Space-Saving 8-Pin SOIC Package**  
- **Power-On Reset (POR) Circuitry:** Ensures reliable startup
