Description and Introduction

Microprocessor voltage monitor with manual reset input. Reset threshold voltage 2.93V. Push-pull active-high reset output. The MAX812SEUS-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX812SEUS-T  
- **Package:** SOT-143  
- **Type:** Microprocessor Supervisor  
- **Reset Threshold Voltage:** 4.63V (adjustable for custom variants)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 8μA (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** Active-Low, Push-Pull  

### **Descriptions:**
The MAX812SEUS-T is a low-power microprocessor reset circuit designed to monitor system power supplies. It asserts a reset signal when the supply voltage drops below a preset threshold, ensuring proper system initialization and preventing erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable reset assertion at 4.63V (adjustable in other variants).  
- **Low Power Consumption:** Only 8μA typical quiescent current.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V.  
- **Push-Pull Reset Output:** No external pull-up resistor required.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures proper reset even at low voltages.  
- **Small SOT-143 Package:** Space-efficient for compact designs.  
- **Industrial Temperature Range:** Operates from -40°C to +85°C.  

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