Description and Introduction

Low Quiescent Current, Programmable-Delay Supervisory Circuit The TPS3808G18DBVR is a voltage supervisor manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 1.8V (fixed threshold)  
- **Threshold Accuracy:** ±1.5% (typical)  
- **Quiescent Current:** 1.1µA (typical)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (200ms min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS3808G18DBVR is a nanopower voltage supervisor designed to monitor system voltages and provide a reset signal when the voltage falls below a preset threshold. It is optimized for low-power applications and ensures reliable system operation.  

### **Features:**  
- Ultra-low power consumption (1.1µA typical)  
- Fixed threshold voltage of 1.8V  
- Push-pull or opendrain reset output options (device variant dependent)  
- Adjustable reset delay time  
- Small SOT-23-5 package  
- Power-on reset generator  
- Immune to short voltage transients  

This device is commonly used in battery-powered systems, portable electronics, and embedded applications requiring reliable voltage monitoring.

Description and Introduction

Low Quiescent Current, Programmable-Delay Supervisory Circuit The TPS3808G18DBVR is a voltage supervisor from Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Part Number:**  
TPS3808G18DBVR  

### **Description:**  
The TPS3808G18DBVR is a nanopower voltage supervisor designed to monitor system voltages in low-power applications. It provides a reset signal when the supply voltage drops below a preset threshold, ensuring proper system operation.  

### **Key Features:**  
- **Supply Voltage Range:** 1.8V (fixed threshold)  
- **Ultra-Low Quiescent Current:** 350nA (typical)  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Adjustable Reset Time Delay (via external capacitor)**  
- **Open-Drain Reset Output**  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Applications:**  
- Battery-powered devices  
- Portable electronics  
- Microprocessor/microcontroller monitoring  
- Industrial and automotive systems  

### **Additional Notes:**  
- The reset output remains active (low) when VDD is below the threshold.  
- The device is available in a small SOT-23 package for space-constrained applications.  

For detailed technical specifications, refer to the official TI datasheet.
