Description and Introduction

220nA Supervisor with 10ms/200ms selectable delay time The TPS3838E18DBVT is a voltage supervisor from Texas Instruments (TI). Here are its key specifications, descriptions, and features:

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

### **Part Number:**  
TPS3838E18DBVT  

### **Description:**  
The TPS3838E18DBVT is an ultra-low-power voltage supervisor (reset IC) designed to monitor supply voltages in battery-powered and low-power applications. It ensures reliable system operation by generating a reset signal when the supply voltage drops below a preset threshold.  

### **Key Features:**  
- **Ultra-Low Quiescent Current:** Typically **350nA**, making it ideal for battery-powered applications.  
- **Fixed Threshold Voltage:** **1.8V** (E18 variant).  
- **Adjustable Reset Time Delay:** Configurable via an external capacitor.  
- **Manual Reset Input:** Allows for external system reset control.  
- **Open-Drain Reset Output:** Active-low (RESET) output.  
- **Wide Operating Voltage Range:** **1.5V to 6.5V**.  
- **Small Package:** **SOT-23-5 (DBV)** for space-constrained designs.  
- **Temperature Range:** **-40°C to +125°C** (industrial-grade).  

### **Applications:**  
- Battery-powered devices  
- Portable electronics  
- Microcontroller (MCU) power monitoring  
- Industrial and automotive systems  

### **Package Type:**  
SOT-23-5 (DBVT)

Description and Introduction

220nA Supervisor with 10ms/200ms selectable delay time The TPS3838E18DBVT is a voltage supervisor from Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS3838E18DBVT  
- **Type:** Voltage Supervisor / Reset IC  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Threshold Voltage:** 1.8V (Fixed)  
- **Operating Voltage Range:** 1.1V to 6.5V  
- **Quiescent Current:** 1.1µA (Typical)  
- **Reset Timeout Period:** 200ms (Typical)  
- **Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The TPS3838E18DBVT is a low-power voltage supervisor designed to monitor system voltage levels. It provides a reset signal to the microprocessor or microcontroller when the supply voltage drops below a preset threshold (1.8V). The device ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Ultra-Low Power Consumption:** 1.1µA typical quiescent current.  
- **Fixed Threshold Voltage:** 1.8V with high accuracy (±1.5%).  
- **Wide Operating Voltage Range:** 1.1V to 6.5V.  
- **Adjustable Reset Delay Time:** 200ms typical (fixed).  
- **Small Package:** SOT-23-5 for space-constrained applications.  
- **No External Components Required:** Simplifies design.  
- **Industrial Temperature Range:** -40°C to +125°C.  
- **Push-Pull Output:** Active-low reset signal.
