Description and Introduction

25 The TPS3707-33DR is a voltage supervisor manufactured by Texas Instruments. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Part Number:** TPS3707-33DR  
- **Type:** Voltage Supervisor / Monitor  
- **Output Configuration:** Open Drain  
- **Number of Voltages Monitored:** 1  
- **Threshold Voltage:** 3.3V (Fixed)  
- **Accuracy:** ±1.5%  
- **Reset Timeout:** Adjustable (External Capacitor)  
- **Operating Voltage Range:** 1.8V to 6.5V  
- **Quiescent Current:** 6µA (Typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**
The TPS3707-33DR is a high-accuracy voltage supervisor designed to monitor power rails in various applications. It features an open-drain reset output and an adjustable reset delay time. The device ensures reliable system operation by asserting a reset signal when the monitored voltage falls below the threshold.

### **Features:**
- **Fixed Threshold Voltage:** 3.3V (with ±1.5% accuracy)  
- **Low Quiescent Current:** 6µA (typical)  
- **Wide Operating Voltage Range:** 1.8V to 6.5V  
- **Adjustable Reset Delay Time:** Configurable via an external capacitor  
- **Open-Drain Reset Output:** Compatible with multiple logic levels  
- **Small Package:** SOIC-8 for space-constrained applications  
- **Robust Performance:** Operates across industrial temperature ranges (-40°C to +125°C)  

This device is commonly used in power management for microcontrollers, DSPs, FPGAs, and other digital systems requiring voltage monitoring.
