5V rail watchdog for automotive ECUs
It asserts an active-low, open-drain reset output when the monitored voltage drops below the 5V threshold, holding the system in reset until the supply recovers and stabilizes.
6-WSON footprint and surface-mount assembly
The 6-WSON package (1.5x1.5 mm body) is a compact, leadless surface-mount package with a thermal pad.
Listed as Active on the product status. The base product number TPS389050 covers a family of threshold-voltage variants, so supply continuity for the 5V version tracks the broader family's production commitment.
