Description and Introduction

Low Cost Power-On Reset and Watchdog Controllers The MAX698CWE is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
- **MAX** (Maxim Integrated)  

### **Part Number:**  
- **MAX698CWE**  

### **Description:**  
The MAX698CWE is a μP (microprocessor) supervisory circuit designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by providing reset signals during power-up, power-down, and brownout conditions.  

### **Key Features:**  
1. **Voltage Monitoring:**  
   - Monitors up to four system voltage rails (VCC, VCC2, VCC3, VCC4).  
   - Adjustable or fixed threshold options for voltage monitoring.  

2. **Reset Functionality:**  
   - Active-low reset output (RESET) with a 140ms (min) delay.  
   - Manual reset input (MR) for external reset triggering.  

3. **Watchdog Timer:**  
   - Integrated watchdog timer with a 1.6-second timeout period.  
   - Prevents system lockup by resetting the μP if not toggled within the timeout period.  

4. **Power-Fail Comparator:**  
   - Early warning power-fail detection (PFI/PFO) for controlled system shutdown.  

5. **Supply Voltage Range:**  
   - Operates from **1.8V to 5.5V**, making it suitable for low-voltage systems.  

6. **Package:**  
   - **16-pin Wide SOIC (CWE)** package.  

7. **Temperature Range:**  
   - Industrial-grade operation: **-40°C to +85°C**.  

8. **Additional Features:**  
   - Low quiescent current (typically **35μA**).  
   - No external components required for basic operation.  

### **Applications:**  
- Embedded systems  
- Industrial controls  
- Automotive electronics  
- Telecommunications equipment  
- Battery-powered devices  

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