Description and Introduction

30 The TPS3705-50DGNR is a high-accuracy voltage detector manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Part Number:** TPS3705-50DGNR  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Voltage Detector (Supervisor)  
- **Detection Voltage:** 5.0V (fixed threshold)  
- **Accuracy:** ±1% (typical)  
- **Operating Voltage Range:** 1.8V to 18V  
- **Quiescent Current:** 1.5µA (typical)  
- **Output Configuration:** Open-Drain  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (200ms typical)  
- **Package:** 8-Pin MSOP (DGNR)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions and Features:**  
- **High-Accuracy Voltage Monitoring:** Provides precise monitoring of supply voltages with ±1% threshold accuracy.  
- **Ultra-Low Power Consumption:** Consumes only 1.5µA (typical) quiescent current, making it suitable for battery-powered applications.  
- **Wide Operating Voltage Range:** Supports monitoring from 1.8V up to 18V.  
- **Open-Drain Reset Output:** Allows flexible interfacing with different logic levels.  
- **Adjustable or Fixed Reset Delay:** Reset timeout can be set using an external capacitor or defaults to a fixed 200ms delay.  
- **Small Form Factor:** Available in an 8-pin MSOP package for space-constrained designs.  
- **Robust Performance:** Operates reliably across a wide temperature range (-40°C to +125°C).  

This device is commonly used in power management applications, such as microcontrollers, DSPs, FPGAs, and other systems requiring voltage supervision.
