Product details

Two-rail monitoring for mixed-voltage boards

The TPS3306-18QDRQ1 is a multi-voltage supervisor that monitors two rails at 1.68 V and 2.93 V. The open-drain, active-low reset output allows wired-OR connection to multiple supervisors.

Automotive-grade temperature range

The 70 ms minimum reset timeout provides enough hold time for the downstream power supplies and oscillators to stabilise after a fault clears.

The 8-SOIC package (3.90 mm width) is a standard, widely stocked footprint with multiple second-source options on the same pinout.

Frequently asked questions

Is TPS3306-18QDRQ1 a direct replacement for TPS3306-18?

The TPS3306-18QDRQ1 is the automotive-qualified (AEC-Q100) variant of the base TPS3306-18. Functionally identical — same thresholds, same reset timeout, same 8-SOIC footprint — but the Q1 device is the one to specify for automotive or extended-temperature designs.

Does TPS3306-18QDRQ1 have a push-pull or open-drain output?

The reset output is open-drain, active low. This allows multiple supervisors to share a common reset bus via a pull-up resistor to the appropriate rail.
