Description and Introduction

3-PIN UP RESET MONITORS The TCM809TENB is a microprocessor supervisory circuit manufactured by Microchip. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Microchip  
- **Type:** Voltage Monitor / Supervisor  
- **Number of Channels:** 1  
- **Reset Threshold Voltage:** Adjustable or Fixed (specific value depends on variant)  
- **Reset Timeout Period:** Typically 140ms (exact value may vary)  
- **Operating Voltage Range:** 1.0V to 5.5V (or as per datasheet)  
- **Output Type:** Active-Low, Push-Pull or Open-Drain (varies by model)  
- **Package:** SOT-23 (3-Lead)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TCM809TENB is a low-power voltage supervisor designed to monitor microprocessor power supplies. It asserts a reset signal when the supply voltage drops below a preset threshold, ensuring proper system operation during power-up, power-down, and brownout conditions.  

### **Features:**  
- Precision voltage monitoring for 3V, 3.3V, or 5V systems (exact threshold depends on variant)  
- Low quiescent current (typically a few microamps)  
- Manual reset input capability (if supported by variant)  
- Guaranteed reset output valid down to VCC = 1.0V  
- Small SOT-23 package for space-constrained applications  
- No external components required for basic operation  

For exact threshold voltages, timing, and variant-specific details, refer to the official Microchip datasheet.
