Description and Introduction

18 The TPS3305-25DR is a voltage supervisor IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range (VDD):** 1.8V to 6.5V  
- **Threshold Voltage (VIT):** 2.5V (fixed)  
- **Output Type:** Active-low, push-pull reset  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8 (DR)  

### **Descriptions:**  
The TPS3305-25DR is a voltage supervisor designed to monitor power supply voltages in microprocessors and digital systems. It ensures proper system operation by generating a reset signal when the supply voltage falls below the threshold.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures accurate reset generation at 2.5V threshold.  
- **Low Quiescent Current:** Typically 35µA, reducing power consumption.  
- **Wide Operating Voltage Range:** Supports 1.8V to 6.5V inputs.  
- **Manual Reset Input:** Allows external reset control.  
- **Power-On Reset (POR) Generator:** Ensures proper startup sequence.  
- **Push-Pull Reset Output:** No external pull-up resistor required.  

This device is commonly used in embedded systems, industrial controls, and consumer electronics for reliable power monitoring.
