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.  

This information is based solely on the provided knowledge base.

Alternative Part Number

  • MAX6718UK18D3+T --: Supervisory circuit with 1.8V threshold and active-low push-pull reset in SOT-23-5, functionally similar to the TPS3838E18DBVT for voltage monitoring applications.
  • APX803L-18SA-7 --: Low-power voltage supervisor with 1.8V detection threshold and active-low reset output, suitable drop-in replacement in compact SOT-23 packages.
  • MCP1316T-18DI/OT --: Voltage supervisor with 1.8V trip point and active-low reset in SOT-23-5, offering comparable supply monitoring performance for the same rail.
  • MAX6715AUTTGD3+T --: Supervisory circuit with similar 1.8V monitoring threshold and reset output in a small SOT23 package; a well-established cross for TI's TPS3838 family.
  • MCP1316T-18AE/TO --: Micropower voltage supervisor with 1.8V trip point and active-low reset, offering comparable supply current and small package for battery-powered designs.
