Description and Introduction

3-PIN UP RESET MONITORS The TCM809SENB is a microprocessor supervisory circuit manufactured by Microchip. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Microchip  
- **Type:** Voltage Supervisor / Reset IC  
- **Reset Threshold Voltage:** Adjustable or fixed options (specific to variant)  
- **Operating Voltage Range:** Typically 1.8V to 5.5V (varies by model)  
- **Reset Timeout Period:** Typically 140ms (varies by variant)  
- **Output Type:** Active-low reset (open-drain or push-pull, depending on variant)  
- **Package:** SOT-23 (3-pin or 5-pin, depending on variant)  
- **Operating Temperature Range:** -40°C to +85°C (industrial grade)  

### **Descriptions:**  
The TCM809SENB is designed to monitor microprocessor power supplies, ensuring stable operation by asserting a reset signal during power-up, power-down, or brownout conditions. It provides reliable system initialization and prevents erratic behavior due to unstable voltage.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures accurate reset assertion at specified thresholds.  
- **Low Power Consumption:** Minimal current draw in active and standby modes.  
- **Manual Reset Input:** Some variants include a manual reset pin for user-initiated resets.  
- **Wide Voltage Range:** Supports operation from 1.8V to 5.5V (varies by model).  
- **Industrial Temperature Range:** Suitable for harsh environments (-40°C to +85°C).  
- **Small Form Factor:** Available in compact SOT-23 packages for space-constrained designs.  

For exact details, refer to the **Microchip datasheet** for the specific TCM809SENB variant.
