Description and Introduction

Very Low Supply Current 3−Pin Microprocessor Reset Monitors The MAX809SN293D3T1G is a microprocessor reset circuit manufactured by ON Semiconductor.  

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

### **Descriptions:**  
The MAX809SN293D3T1G is a low-power voltage supervisor designed to monitor system voltages and provide a reset signal to microprocessors or other logic circuits when the supply voltage drops below a preset threshold (2.93V). It ensures proper system initialization during power-up, power-down, or brownout conditions.  

### **Features:**  
- Precision voltage monitoring (2.93V threshold)  
- Low power consumption (6µA typical)  
- Guaranteed reset output valid down to VCC = 1V  
- No external components required  
- Push-pull reset output (no pull-up resistor needed)  
- Small SOT-23-3 package for space-constrained applications  

This device is commonly used in embedded systems, microcontrollers, and other digital circuits requiring reliable power monitoring.
