Description and Introduction

4-Pin µP Voltage Monitors with Manual Reset Input The MAX812REUS+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** 2.63V, 2.93V, 3.08V, 4.38V, 4.63V  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-143-4  
- **Low Quiescent Current:** 6μA (typ)  
- **Manual Reset Input:** Active-low (MR)  
- **Output Type:** Active-low, push-pull  

### **Descriptions:**  
The MAX812REUS+ monitors the power supply voltage of a microprocessor and provides a reset signal if the voltage drops below a preset threshold. It ensures proper system operation by holding the reset signal until the voltage stabilizes.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **No External Components Required:** Simplifies design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reset integrity.  
- **Small Form Factor:** SOT-143-4 package saves board space.  

This device is commonly used in embedded systems, industrial controls, and portable electronics.
