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.
