Description and Introduction

15 The TPS3306-33DR is a power supply monitor manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 1.8V to 6.5V  
- **Output Voltage (VDD):** 3.3V (fixed)  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** Adjustable via external capacitor (default 200ms)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8 (DR)  

### **Descriptions:**
- The TPS3306-33DR is a supervisory circuit designed to monitor power supply voltages in microprocessor and digital systems.  
- It provides a reset signal to the system when the supply voltage drops below a preset threshold, ensuring proper system initialization.  
- It includes a manual reset input for external control.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures reliable system reset during power-up, power-down, and brownout conditions.  
- **Adjustable Reset Delay:** Allows customization of the reset timeout period.  
- **Manual Reset Input:** Provides an external reset trigger option.  
- **Low Quiescent Current:** Typically 35µA, reducing power consumption.  
- **Wide Operating Voltage Range:** Supports monitoring from 1.8V to 6.5V.  
- **Industrial Temperature Range:** Suitable for harsh environments.  

This device is commonly used in embedded systems, industrial controls, and automotive applications where reliable power monitoring is critical.
