Description and Introduction

3-Pin Microprocessor Reset Circuits The MAX809R is a microprocessor reset circuit manufactured by PHILIPS (now NXP Semiconductors).  

**Specifications:**  
- **Type:** Voltage monitor/reset IC  
- **Reset Threshold Voltage:** 4.65V (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Output Type:** Active-low reset signal (open-drain or push-pull, depending on variant)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some variants)  
- **Package Options:** SOT23, SC70, SOIC  

**Descriptions & Features:**  
- Monitors system voltage and provides a reset signal to the microprocessor when voltage drops below a preset threshold.  
- Ensures proper system initialization during power-up and power-down.  
- Low power consumption.  
- Available in different threshold voltages for various applications.  
- Built-in glitch immunity for noise rejection.  
- Suitable for battery-powered and embedded systems.  

(Note: Exact specifications may vary by variant; always refer to the datasheet for precise details.)
