Description and Introduction

Microprocessor Voltage Monitors with Programmable Voltage Detection The MAX8212CUA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 8-pin μMAX  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-set (e.g., 4.65V, 4.40V, 3.08V, etc.)  
- **Reset Timeout Period:** Adjustable (external capacitor) or fixed (200ms typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typical)  

### **Descriptions:**  
- The MAX8212CUA monitors system voltage and provides a reset signal to the μP during power-up, power-down, or brownout conditions.  
- It ensures proper system operation by holding the μP in reset until the supply voltage stabilizes.  
- Available in a space-saving 8-pin μMAX package.  

### **Features:**  
- **Low Power Consumption:** 5μA typical supply current.  
- **Adjustable Reset Timeout:** Can be set using an external capacitor.  
- **Precision Voltage Monitoring:** Factory-trimmed thresholds for accuracy.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Power-Fail Comparator:** Provides early warning of power loss.

Application Scenarios & Design Considerations

Microprocessor Voltage Monitors with Programmable Voltage Detection

Alternative Part Number

  • TC54VC2102ECB713 --: Voltage supervisor in SOT-23 with similar reset threshold and open-drain output; different series and manufacturer make it easy to distinguish from the source.
  • MCP111-270E/TO --: Low-power voltage detector with comparable threshold and active-low reset, offered in TO-92; a different family and prefix from the MAX part.
  • APX803L-26SA-7 --: Compact SOT-23 voltage supervisor with similar reset function and threshold, from a different vendor and naming series.
  • TL7705ACP --: Widely available voltage supervisor in DIP-8 with similar reset threshold and open-drain output, easy drop-in for many MAX8212 applications.
  • MC33064P-5 --: Low-cost 5V voltage detector/supervisor with comparable threshold accuracy and active-low reset, suitable replacement in monitoring circuits.
  • LTC1232CN8 --: Precision voltage supervisor with adjustable reset threshold and manual reset input, offering similar functionality in an 8-pin package.
