Description and Introduction

3-Pin Microprocessor Reset Circuits The MAX810MEXR-T is a microprocessor reset circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX810MEXR-T  
- **Type:** Voltage Monitor / Reset Circuit  
- **Reset Threshold Voltage Options:** 2.63V, 2.93V, 3.08V, 4.38V, 4.63V (depending on variant)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** 140ms (min)  
- **Output Type:** Active-Low, Push-Pull  
- **Quiescent Current:** 5µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
The MAX810MEXR-T is a low-power microprocessor reset circuit that monitors the power supply voltage and asserts a reset signal when the voltage drops below a preset threshold. It ensures proper system initialization upon power-up or brownout conditions.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Low Power Consumption:** Typically draws 5µA.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures proper reset even at low voltages.  
- **Push-Pull RESET Output:** Eliminates the need for a pull-up resistor.  
- **Small SOT-23 Package:** Space-saving solution for compact designs.  

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

Application Scenarios & Design Considerations

Alternative Part Number

  • ADM810MARTZ-REEL7 --: Pin-compatible microprocessor reset supervisor with similar threshold and active-high reset, from the same product family lineage after Maxim's acquisition by ADI.
  • MCP130-450DI/TO --: Low-cost 3-pin voltage supervisor with comparable reset threshold and open-drain output, suitable drop-in for many MAX810 applications.
  • TL7705ACDR --: Widely available supply voltage supervisor with adjustable threshold and reset output, usable as a functional substitute with minor circuit adjustment.
  • ADM810MARTZ-REEL --: Pin-compatible microprocessor reset supervisor with similar reset threshold and active-high push-pull output, widely available and functionally equivalent.
  • MCP131T-315E/TT --: Low-cost voltage supervisor in SOT-23 with comparable reset threshold and active-high output, suitable drop-in replacement for many MAX810 applications.
  • TPS3808G30DBVR --: Adjustable-delay supervisor with similar supply voltage range and reset output, offering good availability and robust performance as an alternative.
