TPS3808EG01DBVRQ1

Supervisors Overview

The TPS3808EG01DBVRQ1 is an automotive-grade voltage supervisory circuit manufactured by Texas Instruments. It features a typical quiescent current of 600 nA and a threshold accuracy of 1%. The device monitors a single input with a fixed threshold voltage of 405 mV. It provides an open-drain active-low reset output and includes a manual reset input. The reset delay time is fixed at 20 ms. The maximum supply voltage is 6 V, and it operates within a temperature range of -40°C to +125°C. The component is housed in a SOT-23-6 package and holds AEC-Q100 qualification.

Supervisors Feature Summary

• Ultra-low quiescent current consumption for extended battery life
• High threshold accuracy ensures reliable voltage monitoring
• Automotive grade qualification for harsh environment operation

Supervisors Applications

• Battery-powered automotive electronic systems
• Microprocessor power supply supervision
• Embedded control unit voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix 'G01' corresponds to the 405 mV threshold variant when sourcing. Confirm AEC-Q100 qualification status is required for the intended automotive application. Ensure the SOT-23-6 package footprint matches the design layout. Check for RoHS compliance documentation if environmental regulations apply. Validate that the 6 V maximum supply rating suits the system voltage rails.

Supervisors Selection Notes

Select this component when ultra-low standby current is critical for battery efficiency. Choose the G-series for adjustable or low-voltage thresholds compared to fixed E-series options. Consider the 20 ms reset delay timing requirements against system startup needs. Verify the open-drain output compatibility with the downstream logic levels. Ensure the operating temperature range covers the expected ambient conditions.

Supervisors Part Context

This part belongs to the TPS3808 family of microprocessor supervisory circuits from Texas Instruments. The family offers various threshold voltages and quiescent current options. The Q1 suffix indicates automotive grade qualification. The DBVR package denotes a tape-and-reel SOT-23-6 configuration. This series supports both manual reset and power-on reset functionalities.

Supervisors Replacement Considerations

TPS3808G01DBVRQ1 shares identical electrical specifications and pinout. TPS3808G01DBVT is the same device in a different package variant.
