TPS389050GQDSERQ1

Supervisors Overview

The TPS389050GQDSERQ1 is a single-channel voltage supervisor from the TPS3890-Q1 family, designed for automotive applications. It features an open-drain or open-collector output and provides simple reset and power-on reset functions with a low-active signal. The device monitors a supply voltage threshold of 5V and operates within a junction temperature range of -40°C to 125°C. It is housed in a compact 6-WSON (1.5x1.5) package and holds AEC-Q100 qualification.

Supervisors Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Open-drain or open-collector output configuration
• Compact 6-WSON surface-mount packaging

Supervisors Applications

• Automotive electronic system monitoring
• Microcontroller reset supervision
• Power management circuit protection

Supervisors Procurement Notes

Verify the specific suffix GQDSERQ1 against official Texas Instruments documentation to confirm exact manufacturing lot codes and tape-and-reel specifications. Ensure compatibility with your assembly process by checking the datasheet for moisture sensitivity level and reflow soldering profiles. Confirm that the open-drain output requirements match your system design before finalizing procurement.

Supervisors Selection Notes

Select this component when a 5V threshold is required for automotive-grade voltage supervision. The open-drain output allows for flexible logic interfacing. Consider the 6-WSON package size for space-constrained designs. Verify that the operating temperature range meets your application's environmental demands and that the single-channel capability suffices for your monitoring needs.
