Description and Introduction

4-Pin µP Voltage Monitors with Manual Reset Input The MAX812LEUS is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX812LEUS  
- **Type:** Microprocessor Supervisor  
- **Package:** SOT-143-4  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** 2.63V, 2.93V, 3.08V, 4.38V, 4.63V (factory-set)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  

### **Descriptions:**
- The MAX812LEUS monitors microprocessor power supplies and provides a reset signal if the voltage drops below a preset threshold.  
- It ensures proper system operation by holding the microprocessor in reset until the supply voltage stabilizes.  
- Available in a small SOT-143-4 package, making it suitable for space-constrained applications.  

### **Features:**
- **Low Power Consumption:** Only 6μA typical supply current.  
- **Precision Voltage Monitoring:** Factory-trimmed reset threshold options.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **No External Components Required:** Simplifies circuit design.  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications.
