Description and Introduction

4-Pin レP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay The MAX821RUS-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** SOT-23-4  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  

### **Descriptions:**  
The MAX821RUS-T monitors system voltages and provides a reset signal to the microprocessor when the supply voltage drops below a preset threshold. It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Low Power Consumption:** Only 6μA typical quiescent current.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V.  
- **Precision Voltage Monitoring:** ±1.5% reset threshold accuracy.  
- **Manual Reset Input:** Allows external reset control.  
- **Small Form Factor:** Available in a compact SOT-23-4 package.  
- **No External Components Required:** Simplifies design.  

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

Application Scenarios & Design Considerations

4-Pin レP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay

Alternative Part Number

  • TPS3700DGKR --: Voltage supervisor with adjustable threshold and open-drain reset output, functionally similar to the MAX821R in a small package.
  • MCP1316T-29FE/OT --: Low-power voltage detector/supervisor with reset output, suitable replacement for supply monitoring applications.
  • APX803L-29SA-7 --: Compact voltage supervisor with active-low reset, offering comparable threshold monitoring in a SOT-23 package.
  • ADM811TARTZ-REEL7 --: Pin-compatible voltage supervisor with similar reset threshold and active-low reset, from the same company that acquired Maxim.
  • TPS3808G01DBVR --: Adjustable-threshold supervisor in SOT-23 with open-drain reset, widely available and functionally similar.
  • MCP131T-315E/TO --: Low-cost voltage supervisor with comparable reset threshold and active-low output in a small package.
