1.4V threshold supervisor for cold-hardened rails
The 5µs typical propagation delay catches fast supply transients before the downstream processor or FPGA corrupts its state. The open-drain output lets you wire-OR the reset signal with other supervisors or pull it up to a different voltage rail.
Military temperature range — avionics and downhole fit
The SC-70-5 package keeps the board footprint small — about 2.1 mm × 2.0 mm — which helps when you are packing multiple supervisors into a dense backplane or remote sensor node.
Listed as Active in the product status. The base product number TPS3803 covers multiple threshold-voltage variants in the same SC-70-5 footprint, so if the rail voltage changes in a future spin, the PCB layout stays the same.
