Description and Introduction

Quad Voltage Monitor with Four Outputs in µMax Package The **MAX6338MUB+** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual data:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor Voltage Monitor / Supervisor  
- **Package:** 10-μMAX (3mm x 5mm)  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (over temperature)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (140ms min)  
- **Manual Reset Input:** Yes (active-low)  
- **Power-On Reset (POR):** Yes  
- **Watchdog Timer:** Yes (programmable timeout: 1.6ms to 102s)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX6338MUB+ is a low-power μP supervisor that monitors system voltage and provides a reset signal to the processor if the voltage falls below a preset threshold. It includes a watchdog timer to detect software crashes and a manual reset input for user-initiated system resets.  

### **Features:**  
- **Voltage Monitoring:** Monitors VCC for undervoltage conditions.  
- **Adjustable Reset Timeout:** Configurable via an external capacitor.  
- **Watchdog Timer:** Ensures system integrity by resetting the μP if software fails to respond.  
- **Manual Reset (MR) Input:** Allows external push-button reset.  
- **Low Quiescent Current:** Typically 25μA (ideal for battery-powered systems).  
- **Wide Operating Voltage Range:** Supports 1.6V to 5.5V systems.  
- **Small Footprint:** 10-μMAX package for space-constrained applications.
