Description and Introduction

Low-Power, Single/Dual-Voltage µP Reset Circuits with Capacitor-Adjustable Reset Timeout Delay The MAX6420UK26+T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6420UK26+T  
- **Type:** Voltage Monitor / Supervisor  
- **Reset Threshold Voltage:** 2.63V (fixed)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-5  

### **Descriptions:**  
The MAX6420UK26+T monitors the voltage of a microprocessor or digital system and asserts a reset signal when the voltage drops below a preset threshold (2.63V). It ensures proper system operation by holding the reset signal until the supply voltage stabilizes.  

### **Features:**  
- **Precision Voltage Monitoring:** Guaranteed reset threshold accuracy of ±1.5%.  
- **Low Quiescent Current:** 6μA (typical).  
- **No External Components Required:** Simplifies design.  
- **Push-Pull RESET Output:** Eliminates the need for a pull-up resistor.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Small Form Factor:** Available in a compact SOT23-5 package.  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications where reliable power monitoring is critical.
