Description and Introduction

Low Quiescent Current, Programmable-Delay Supervisory Circuit 6-WSON -40 to 125 The TPS3808G18DRVR is a voltage supervisor IC manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Part Number:** TPS3808G18DRVR  
- **Type:** Voltage Supervisor / Reset IC  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Inputs:** 1  
- **Reset Threshold Voltage:** 1.8V (Fixed)  
- **Supply Voltage Range:** 1.5V to 6.5V  
- **Quiescent Current:** 1.5µA (Typical)  
- **Reset Timeout Period:** Adjustable via External Capacitor (Default: 200ms)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DRV)  

### **Descriptions:**
The TPS3808G18DRVR is a low-power voltage supervisor designed to monitor system voltages and provide a reset signal when the supply voltage falls below a preset threshold (1.8V in this case). It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.

### **Features:**
- **Ultra-Low Power Consumption:** 1.5µA typical quiescent current.  
- **Fixed Threshold Voltage:** 1.8V with high accuracy (±1.5%).  
- **Adjustable Reset Delay:** Configurable via an external capacitor.  
- **Wide Operating Voltage Range:** 1.5V to 6.5V.  
- **Small Form Factor:** Available in a compact SOT-23-5 package.  
- **Push-Pull Output:** No external pull-up resistor required.  
- **Temperature Stability:** Operates reliably across -40°C to +125°C.  

This device is commonly used in battery-powered applications, microcontrollers, DSPs, and other systems requiring reliable voltage monitoring.
