Description and Introduction

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset The MAX824L is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-set (e.g., 4.63V, 4.38V, 3.08V, 2.93V, 2.63V, 2.32V, etc.)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 6μA (typical)  
- **Output Type:** Active-low, push-pull reset output  
- **Package Options:** 3-Pin SOT23  

### **Descriptions:**  
The MAX824L monitors the power supply voltage of a microprocessor or microcontroller and asserts a reset signal when the voltage drops below a preset threshold. It ensures proper system initialization during power-up, power-down, and brownout conditions.  

### **Features:**  
- **Low Power Consumption:** Only 6μA typical supply current.  
- **Precision Voltage Monitoring:** Factory-trimmed threshold options ensure accuracy.  
- **No External Components Required:** Simplifies circuit design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **Small Form Factor:** Available in a compact 3-Pin SOT23 package.  
- **Manual Reset Capability:** Some variants support an external reset input (not applicable to all versions).  

The MAX824L is commonly used in battery-powered devices, embedded systems, and portable electronics requiring reliable power monitoring.  

(Note: Specific threshold voltages and features may vary by variant. Always refer to the official datasheet for exact specifications.)
