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.","metaTitle":"TPS3306-18QDRQ1 Multi-Voltage Supervisor, AEC-Q100","metaDescription":"Texas Instruments TPS3306-18QDRQ1 multi-voltage supervisor monitors two rails at 1.68V and 2.93V.
