Description and Introduction

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset The MAX825MEUK-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual details about this part:

### **Manufacturer:**  
Maxim Integrated (now part of Analog Devices)

### **Part Number:**  
MAX825MEUK-T  

### **Description:**  
The MAX825MEUK-T is a low-power microprocessor supervisory circuit designed to monitor system power supplies and provide reset signals to μPs and other logic devices. It ensures proper system operation during power-up, power-down, and brownout conditions.

### **Key Features:**  
- **Reset Threshold Options:** Factory-trimmed to 4.38V, 4.63V, or 4.88V  
- **Low Quiescent Current:** 5μA (typical)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Manual Reset Input:** Allows external pushbutton reset control  
- **Power-Fail Comparator:** Provides early warning of power failure  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Package:** SOT23-5  

### **Applications:**  
- Microprocessor and microcontroller systems  
- Embedded controllers  
- Industrial and automotive systems  
- Battery-powered equipment  

### **Package Type:**  
SOT23-5  

### **Operating Temperature Range:**  
- **Extended Industrial:** -40°C to +85°C  

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

Application Scenarios & Design Considerations

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset

Alternative Part Number

  • ADM706TARZ --: Pin-compatible microprocessor supervisory circuit with similar reset and watchdog functions, widely available and a direct functional drop-in for the MAX825 family.
  • TPS3705-33DR --: Supervisory/reset IC offering comparable voltage monitoring and reset timing, suitable replacement when exact MAX825 features are not all required.
  • MC33064D-5G --: Undervoltage sensing/reset IC with similar supply monitoring role, low cost and easy availability as a fallback alternative.
  • TPS3808G01DBVR --: Adjustable-threshold voltage supervisor with programmable delay in SOT-23-6, a common drop-in style replacement for MAX825 monitoring functions.
  • MCP1316T-29FE/OT --: Low-power voltage supervisor with manual reset and watchdog in SOT-23-5, suitable alternative for MAX825 reset supervision applications.
