Description and Introduction

Low Quiescent Current, Programmable-Delay Supervisory Circuit The TPS3808G25DBVR is a voltage supervisor (or reset IC) manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage Range:** 1.8V to 6.5V  
- **Threshold Voltage Options:** 2.5V (fixed)  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Quiescent Current:** 1.1µA (typical)  
- **Output Type:** Active-low, open-drain  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**
The TPS3808G25DBVR 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 commonly used in battery-powered and low-power applications to ensure proper system initialization and recovery during power-up, power-down, or brownout conditions.

### **Features:**
- Ultra-low power consumption (1.1µA typical quiescent current)  
- Fixed threshold voltage of 2.5V  
- Open-drain reset output (requires external pull-up resistor)  
- Small SOT-23-5 package for space-constrained applications  
- High accuracy (±1.5%) over temperature  
- Wide operating voltage range (1.8V to 6.5V)  
- Immune to short voltage transients  
- No external components required (except pull-up resistor for reset output)  

This information is strictly based on TI's official datasheet and product documentation.
