Description and Introduction

Very Low Supply Current 3-Pin Microprocessor Reset Monitors The MAX809RTR is a microprocessor reset circuit manufactured by ON Semiconductor.  

### **Specifications:**  
- **Type:** Voltage Monitor  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Threshold Voltage Options:** 2.63V, 2.93V, 3.08V, 4.38V, 4.63V  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Timeout Period:** 140ms (min)  
- **Quiescent Current:** 5µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
The MAX809RTR is a low-power voltage monitor designed to provide a reset signal to microprocessors and other digital systems during power-up, power-down, or brownout conditions. It ensures reliable system operation by holding the reset signal active until the supply voltage stabilizes.  

### **Features:**  
- Precision voltage monitoring  
- Low power consumption  
- Guaranteed reset output valid down to VCC = 1V  
- No external components required  
- Small SOT-23-3 package for space-constrained applications  
- Immune to short power supply glitches  

This device is commonly used in embedded systems, automotive electronics, and industrial controls.
