Description and Introduction

Pin-Selectable Watchdog Timers The **MAX6373KA+T** is a microprocessor (µP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Type:** µP Supervisory Circuit  
- **Package:** SOT-23-8  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Reset Threshold Options:** Adjustable or factory-set (e.g., 2.32V, 2.93V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6µA (typical)  

### **Descriptions:**
- The MAX6373KA+T monitors microprocessor power supplies and generates a reset signal if the voltage drops below a preset threshold.  
- It ensures reliable system operation by holding the µP in reset until the supply voltage stabilizes.  
- Available in a small **SOT-23-8** package, making it suitable for space-constrained applications.  

### **Features:**
- **Low Power Consumption:** Only 6µA typical supply current.  
- **Adjustable or Fixed Threshold:** Supports multiple reset voltage options.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Power-On Reset (POR):** Ensures proper startup when power is applied.  
- **Wide Operating Voltage Range:** Works from 1.6V to 5.5V.  
- **Industrial Temperature Range:** Operates from -40°C to +85°C.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations
