Product details

Dual-voltage supervisor for 3.3V and 5V automotive rails

The TPS3306-33QDRQ1 is a Texas Instruments multi-voltage supervisor that monitors two supply rails simultaneously — a 2.93V threshold for a 3.3V bus and a 4.55V threshold for a 5V bus, with an active-low open-drain reset output that pulls low on any undervoltage condition. This part is qualified to AEC-Q100, making it suitable for automotive applications that require documented PPAP and IATF 16949 compliance.

The reset output holds low for a minimum of 70 ms after both monitored voltages rise above their thresholds, ensuring downstream devices complete their power-on reset sequence before release.

Frequently asked questions

How can I order TPS3306-33QDRQ1 or check current pricing?

The TPS3306-33QDRQ1 is an active Texas Instruments part. We source it to order against your BOM quantity; submit an RFQ for current pricing and lead-time confirmation.

Does TPS3306-33QDRQ1 monitor both 2.93V and 4.55V thresholds simultaneously?

Yes, the device monitors two independent voltage inputs with thresholds of 2.93V and 4.55V, corresponding to 3.3V and 5V nominal rails.

What is the reset timeout of TPS3306-33QDRQ1?

The reset output holds low for a minimum of 70 ms after both voltages are valid, giving downstream logic time to initialize.

Is TPS3306-33QDRQ1 AEC-Q100 qualified?

Yes, it is part of the Automotive, AEC-Q100 series, meeting the qualification requirements for automotive-grade PPAP submission.

What are the substitutes for TPS3306-33QDRQ1?

Direct functional substitutes are limited because the TPS3306-33QDRQ1 monitors two specific thresholds (2.93V and 4.55V) with a 70 ms timeout. The TLV803 series (e.g., TLV803EA29VDBZR) are single-voltage supervisors with different timeout options and are not pin-compatible dual-channel replacements.
