Description and Introduction

5-Pin Microprocessor Supervisory Circuits with Watchdog Timer and Manual Reset The MAX824REXK+T is a microprocessor (μP) supervisory circuit manufactured by MAXIM.  

### **Specifications:**  
- **Supply Voltage (VCC):** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.575V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-5  
- **Output Type:** Active-low, push-pull RESET  
- **Quiescent Current:** 5μA (typ)  

### **Descriptions:**  
The MAX824REXK+T monitors the power supply voltage of a microprocessor and provides 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 quiescent current (5μA)  
- Precision voltage monitoring  
- No external components required (fixed threshold versions)  
- Guaranteed reset output valid down to VCC = 1V  
- Small SOT23-5 package  
- Power-on reset pulse generator  

This device is commonly used in embedded systems, portable electronics, and battery-powered applications.
