Description and Introduction

3-Pin Microcontroller Reset Monitors The TCM809MVLB713 is a voltage supervisor (microprocessor reset circuit) manufactured by **Microchip Technology**.  

### **Key Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (specific to variant)  
- **Output Type:** Active-low reset (open-drain or push-pull, depending on variant)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23 (3-lead)  
- **Low Quiescent Current:** Typically 5µA (varies by model)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some variants)  

### **Features:**  
- Precision voltage monitoring for microcontrollers and DSPs  
- Manual reset input capability (varies by model)  
- Power-on reset (POR) functionality  
- Guaranteed reset output down to VCC = 1V  
- Small form factor for space-constrained applications  

For exact threshold voltages and variant-specific details, refer to the **Microchip datasheet** for the **TCM809 series**.

Application Scenarios & Design Considerations

3-Pin Microcontroller Reset Monitors

Alternative Part Number

  • MAX809MEUR+T --: Pin-compatible 3-pin reset supervisor with 4.38V threshold, same SOT-23 package and active-low push-pull output, widely used as a direct TCM809 replacement.
  • APX809S-44SA-7 --: Low-cost 3-pin microprocessor reset monitor with 4.4V trip point in SOT-23, functionally equivalent to the TCM809M and readily available.
  • MCP809M-315E/TO --: Microchip's own reset supervisor family with similar 4.4V threshold and active-low output, offering a same-vendor alternative with comparable specifications.
