Description and Introduction

4-Pin Micropower Voltage Monitors The MAX837EUS-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-4  
- **Low Quiescent Current:** 6μA (typ)  
- **Manual Reset Input:** Yes (active-low)  

### **Descriptions:**  
The MAX837EUS-T monitors system voltage and provides a reset signal to the microprocessor when the supply voltage falls below a preset threshold. It ensures reliable system operation by holding the reset signal active until the voltage stabilizes.  

### **Features:**  
- Precision voltage monitoring  
- Adjustable or factory-set reset threshold  
- Low power consumption  
- Guaranteed reset output valid down to VCC = 1V  
- Manual reset capability  
- No external components required for fixed threshold versions  

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