Description and Introduction

Microprocessor Supervisory Circuits The MAX693CWE+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX693CWE+  
- **Package:** 16-SOIC (Wide)  
- **Type:** Microprocessor Supervisor  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (200ms min)  
- **Watchdog Timer:** Programmable (1.6s to 160s)  
- **Manual Reset Input:** Yes  
- **Battery Backup Switch:** Yes (for CMOS RAM)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX693CWE+ is designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal when the supply voltage falls below a specified threshold. It includes a watchdog timer, battery backup switch, and manual reset input for enhanced system reliability.

### **Features:**
- **Low Supply Current:** 40μA (typical)  
- **Adjustable Reset Threshold:** Allows customization for different voltage levels  
- **Battery Backup Control:** Automatically switches to backup battery when primary power fails  
- **Watchdog Timer:** Prevents system lockup by requiring periodic toggling  
- **Manual Reset Input:** Allows external reset triggering  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems  
- **Space-Saving Package:** 16-pin SOIC (Wide)  

This device is commonly used in embedded systems, industrial controls, and battery-backed applications requiring reliable power monitoring.
