Description and Introduction

5V / 12V (15V) Dedicated Microprocessor Voltage Monitors The MAX8215EPD is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX8215EPD  
- **Package:** 14-Pin PDIP (Plastic Dual In-Line Package)  
- **Type:** Microprocessor Supervisor  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (over temperature)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (200ms typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  

### **Descriptions:**  
The MAX8215EPD is a low-power microprocessor supervisory circuit designed to monitor system power supply voltages and provide a reset signal to the μP during power-up, power-down, or brownout conditions. It ensures reliable system operation by holding the μP in reset until the supply voltage stabilizes.  

### **Features:**  
- **Low-Power Operation:** Consumes only 5μA (typical) quiescent current.  
- **Wide Operating Voltage Range:** Works from 1.2V to 5.5V.  
- **Precision Voltage Monitoring:** ±1.5% threshold accuracy.  
- **Adjustable or Fixed Reset Timeout:** User-selectable via external capacitor or fixed at ~200ms.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Power-Fail Comparator:** Provides early warning of impending power loss.  
- **Battery Backup Support:** Can monitor a backup battery voltage.  
- **14-Pin PDIP Package:** Easy-to-use through-hole mounting.  

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

Application Scenarios & Design Considerations

Alternative Part Number

  • ADM8696AN --: Quad voltage monitor/supervisor with similar functionality and DIP package, pin-compatible in many designs.
  • LTC2912CDDB --: Multi-voltage supervisor offering comparable monitoring thresholds and open-drain outputs.
  • TPS3705-33D --: Voltage supervisor with similar supply monitoring function, widely available and cost-effective substitute.
  • ADM8696ARWZ --: Pin-compatible multi-voltage supervisor with similar reset and watchdog functions, widely available from a major supplier.
  • LTC1232CN8 --: Microprocessor supervisory circuit offering comparable reset and watchdog features in a DIP package.
  • TL7705ACP --: Classic low-cost supply voltage supervisor with reset output, suitable for similar monitoring roles though with fewer integrated functions.
