TPS3808EG18DBVRQ1

Supervisors Overview

The TPS3808EG18DBVRQ1 is a voltage supervisory circuit from Texas Instruments, designed for automotive applications. It features a fixed threshold voltage of 1.67 V and supports a maximum supply voltage of 6 V. The device offers programmable reset delay times of 1.25 ms, 300 ms, or 830 ms. It operates within a temperature range of -40°C to +125°C and has an accuracy of 0.5%. The component utilizes an SOT-23-6 package and draws a typical static current of 600 nA.

Supervisors Feature Summary

• Manual reset input capability
• Open drain output configuration
• Automotive qualification compliance

Supervisors Applications

• Automotive power supply monitoring
• Microcontroller system supervision
• Battery backup circuit protection

Supervisors Procurement Notes

Verify the specific suffix 'EG18' confirms the 1.67 V threshold and 1.25/300/830 ms delay options. Confirm AEC-Q100 qualification status for automotive use. Check RoHS compliance details. Ensure the SOT-23-6 package matches PCB footprint requirements. Validate operating temperature range suitability for the target environment.

Supervisors Selection Notes

Select this part when a fixed 1.67 V threshold is required with specific programmable delays. Consider the low quiescent current for battery-sensitive designs. Verify compatibility with the system's maximum supply voltage of 6 V. Ensure the open-drain output interface aligns with the downstream logic requirements.

Supervisors Part Context

This component belongs to the TPS3808E series of low IQ programmable-delay supervisors. It is distinct from the G-series variants which may offer adjustable thresholds or different delay ranges. The Q1 suffix indicates automotive grade qualification. The DBVR package denotes the SOT-23-6 surface-mount form factor.

Supervisors Replacement Considerations

TPS3808G18DBVRQ1: Similar automotive supervisor but may have different delay options (1.25 ms to 10 s) and higher max voltage (6.5 V). Verify threshold and delay compatibility before substitution.
