Description and Introduction

Five Universal Voltage Monitors The MAX8214ACPE is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- Maxim Integrated (now Analog Devices)  

### **Part Number:**  
- MAX8214ACPE  

### **Package:**  
- 16-pin PDIP (Plastic Dual In-Line Package)  

### **Description:**  
The MAX8214ACPE is a precision voltage monitor designed to ensure proper system operation in μP and digital systems. It provides power-on reset (POR) signals, watchdog timer functionality, and manual reset capability.  

### **Key Features:**  
1. **Precision Voltage Monitoring:**  
   - Monitors +5V, +3.3V, or adjustable power supplies.  
   - Guaranteed reset threshold accuracy (±1.5% for MAX8214A).  

2. **Power-On Reset (POR):**  
   - Generates a reset signal when VCC falls below a preset threshold.  
   - Reset timeout period is internally fixed or adjustable.  

3. **Watchdog Timer:**  
   - Monitors μP activity; triggers reset if no activity is detected within a set time.  
   - Watchdog timeout period is programmable.  

4. **Manual Reset Input:**  
   - Allows a pushbutton to initiate a system reset.  

5. **Low-Power Operation:**  
   - Low quiescent current (typically 50μA).  

6. **Wide Operating Voltage Range:**  
   - Operates from 1V to 5.5V.  

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

8. **Output Options:**  
   - Active-low or active-high reset output.  

### **Applications:**  
- Microprocessor and microcontroller systems.  
- Embedded controllers.  
- Critical power supply monitoring.  
- Industrial and automotive electronics.  

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

Application Scenarios & Design Considerations

Five Universal Voltage Monitors

Alternative Part Number

  • ADM8696AN --: Pin-compatible microprocessor supervisory circuit with similar voltage monitoring and reset functions, widely available from an established vendor.
  • TL7705ACP --: Classic 5V supply voltage supervisor in DIP-8 with adjustable reset delay, a common drop-in style replacement for supervisory ICs.
  • MC34064P-5 --: Low-cost 5V undervoltage sensing circuit in DIP package offering basic reset generation for similar supervisory applications.
  • MC33064P --: Low-cost 5V undervoltage sensing circuit in DIP package, suitable for basic reset/supervisory duty where full MAX8214 feature set is not required.
