Description and Introduction

TRIPLE VOLTAGE AND CURRENT SUPERVISOR The part **TSM111CDT** is manufactured by **STMicroelectronics (ST)**.  

### **Specifications:**  
- **Type:** Voltage Supervisor IC  
- **Package:** SOT-23-5  
- **Output Type:** Active-Low, Open Drain  
- **Number of Voltages Monitored:** 1  
- **Reset Threshold Voltage:** Adjustable or Fixed (depending on variant)  
- **Operating Voltage Range:** Typically 1.2V to 5.5V  
- **Reset Timeout Period:** Adjustable or Fixed (varies by model)  
- **Operating Temperature Range:** -40°C to +85°C (Industrial)  

### **Descriptions & Features:**  
- Monitors a single voltage rail and provides a reset signal when the voltage falls below a preset threshold.  
- Open-drain reset output for flexible interfacing.  
- Low quiescent current, making it suitable for battery-powered applications.  
- Available in fixed or adjustable threshold variants.  
- Used in microcontrollers, DSPs, and other digital systems requiring power-on reset functionality.  
- Small SOT-23-5 package for space-constrained designs.  

For exact threshold values and timing details, refer to the official **STMicroelectronics datasheet** for the specific variant of **TSM111CDT**.

Application Scenarios & Design Considerations

TRIPLE VOLTAGE AND CURRENT SUPERVISOR

Alternative Part Number

  • TL431CDT --: Adjustable shunt voltage reference in the same SO-8 package family, widely available and functionally similar for reference/comparator applications.
  • LM393DT --: Dual comparator in SO-8, a common substitute when the TSM111 is used for voltage monitoring/comparison functions.
  • TSM101CDT --: Similar voltage/current controller from ST's TSM10x family with comparable function and package, offering a close functional match.
