1.71V threshold supervisor for 1.8V rails
The open-drain, active-low output stays low for a minimum of 10ms after the rail recovers, giving the downstream MCU or FPGA time to stabilise before release. This part is a basic voltage supervisor — no watchdog timer, no manual reset — just a clean brown-out reset for a single low-voltage rail.
Industrial temp and SOT-23-5 footprint
The SOT-23-5 package (SC-74A) is a common small-outline footprint that routes easily on two-layer boards; the supply pin needs a 0.1µF ceramic within 5mm for decoupling, and the open-drain output pulls up to the monitored rail or a separate 3.3V logic rail through a 10kΩ resistor.
The SOT-23-5 package is widely used across TI's supervisor family, which means the supply base is broad and the part is stocked across multiple distribution channels.
Sourcing and provenance
Sourced through independent distribution, each reel is traceable to a verified supply chain. The date-code laser etch on the body should match TI's standard font and marking layout — any deviation flags a suspect part.
