Product details

AEC-Q100 grade-1 reset for 5V automotive rails

The 20ms minimum reset timeout holds the microprocessor in reset long enough for the supply to stabilise, preventing brown-out false starts on power-up.

4.55V threshold — the 5V rail watchdog

The 4.55V threshold sits 9% below the nominal 5.0V rail, giving enough margin to ignore normal ripple while still catching a sagging supply before the downstream logic enters an undefined state.

SOT-23-6 footprint and supply posture

Housed in a SOT-23-6 package (supplier device package SOT-23-6), surface-mount, with a standard 0.95mm pin pitch that routes easily on two-layer automotive PCBs. Lifecycle status is Active — no last-time-buy or NRND flags, so the part is available for current and new production programs without obsolescence risk.

Frequently asked questions

Is TPS3813I50QDBVRQ1 automotive qualified?

Yes, it is part of the Automotive, AEC-Q100 series, which means it has passed the AEC-Q100 stress tests for automotive-grade reliability. The OEM auditor will expect PPAP documentation — this part supports that submission.

What is the TPS3813I50QDBVRQ1 reset output type?

The reset output is Active Low, open drain or open collector. This allows the output to be pulled up to a different voltage than the monitored rail, common in mixed-voltage automotive ECUs.
