Description and Introduction

SC70/µDFN, Single/Dual Low-Voltage, Low-Power µP Reset Circuits The **MAX6381XR23D3+T** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6381XR23D3+T  
- **Type:** Voltage Monitor/Supervisory Circuit  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Threshold Voltage:** 2.315V (fixed)  
- **Accuracy:** ±1.5% (over temperature)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** 140ms (min)  
- **Quiescent Current:** 3.5μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-3  

### **Descriptions:**
- The **MAX6381XR23D3+T** is a low-power voltage monitor designed to ensure proper system operation by monitoring the power supply and generating a reset signal when the voltage falls below a preset threshold.  
- It is commonly used in **microprocessor-based systems**, **portable devices**, and **battery-powered applications** to prevent data corruption during power-up, power-down, or brownout conditions.  

### **Features:**
- **Ultra-Low Power Consumption:** Only **3.5μA** (typical) supply current.  
- **Precision Voltage Monitoring:** Fixed threshold of **2.315V** with **±1.5%** accuracy.  
- **No External Components Required:** Simplifies design and reduces board space.  
- **Guaranteed Reset Assertion Down to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **Push-Pull RESET Output:** Active-low reset signal with no external pull-up resistor needed.  
- **Small Form Factor:** Available in a **SOT23-3** package for space-constrained applications.  

This device is ideal for applications requiring **battery monitoring**, **power supply supervision**, and **system reset control**.
