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 (1.575V, 2.32V, 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:** SOT23-4  
- **Low Quiescent Current:** 5μA (typ)  

### **Descriptions:**  
The MAX837EUS+T monitors system voltage and generates a reset signal when the voltage falls below a preset threshold, ensuring proper μP operation. It features an active-low reset output and is designed for low-power applications.  

### **Features:**  
- Precision voltage monitoring  
- Adjustable or factory-set reset thresholds  
- Low supply current (5μA typical)  
- Guaranteed reset output down to VCC = 1V  
- No external components required (fixed threshold versions)  
- Small SOT23-4 package  

This device is commonly used in battery-powered systems, embedded controllers, and portable electronics.
