Description and Introduction

1.5-V Processor Supervisory Circuit The TPS3126E15DBVR is a voltage supervisor IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Function:** Monitors voltage levels and provides a reset signal  
- **Threshold Voltage:** 1.5V (fixed)  
- **Output Type:** Active-low, push-pull  
- **Operating Voltage Range:** 0.7V to 6V  
- **Reset Timeout Period:** Adjustable or fixed (depending on variant)  
- **Package:** SOT-23-5 (DBV)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The TPS3126E15DBVR is a voltage supervisor designed to monitor system voltages and generate a reset signal when the voltage falls below a predefined threshold (1.5V in this case).  
- It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  
- The active-low reset output is push-pull, eliminating the need for an external pull-up resistor.  

### **Features:**  
- **Precision Voltage Monitoring:** Accurate threshold detection (±1.5% typical).  
- **Low Quiescent Current:** Typically 3µA, helping conserve power.  
- **Wide Operating Voltage Range:** Supports monitoring from 0.7V to 6V.  
- **Small Form Factor:** SOT-23-5 package for space-constrained applications.  
- **No External Components Required:** Simplifies design and reduces BOM cost.  
- **Industrial Temperature Range:** Reliable performance in harsh environments.  

This IC is commonly used in microcontrollers, DSPs, FPGAs, and other digital systems requiring reliable power monitoring.
