Description and Introduction

Microprocessor voltage monitor with manual reset input. Reset threshold voltage 4.38V. Push-pull active-high reset output. The MAX812MEUS-T 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)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-143-4  
- **Low Quiescent Current:** 6μA (typ)  
- **Manual Reset Input:** Yes (active-low)  
- **Output Type:** Active-low, open-drain  

### **Descriptions:**  
The MAX812MEUS-T monitors microprocessor power supply voltages and generates a reset signal if the voltage drops below a preset threshold. It ensures reliable system operation by holding the reset signal active for a minimum of 140ms after the voltage rises above the threshold.  

### **Features:**  
- Precision voltage monitoring  
- Guaranteed reset output down to VCC = 1V  
- Manual reset input for external control  
- Open-drain reset output (requires pull-up resistor)  
- Low power consumption  
- No external components required  

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