Description and Introduction

Very Low Supply Current 3-Pin Microprocessor Reset Monitors The MAX809LTR is a microprocessor reset circuit manufactured by ONS (ON Semiconductor).  

### **Specifications:**  
- **Type:** Voltage Monitor (Reset IC)  
- **Reset Threshold Voltage Options:** 2.63V, 2.93V, 3.08V, 4.38V, 4.63V  
- **Reset Timeout Period:** 140ms (min), 280ms (max)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 6µA (typical)  
- **Output Type:** Active-Low, Push-Pull  
- **Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
The MAX809LTR is a low-power voltage monitor designed to provide a reset signal to microprocessors or other digital systems when the supply voltage drops below a preset threshold. It ensures proper system initialization upon power-up or brownout conditions.  

### **Features:**  
- Precision voltage monitoring  
- Low power consumption  
- Guaranteed reset output valid down to VCC = 1V  
- No external components required  
- Available in multiple threshold voltages  
- Push-pull output (no external pull-up resistor needed)  
- Small SOT-23-3 package  

This information is based on the manufacturer's datasheet and specifications.
