The TPS3808G18QDBVRQ1 is a Texas Instruments simple reset/power-on reset IC with a fixed 1.67 V threshold, active-low open-drain output, and an adjustable reset timeout. The 1.67 V threshold targets 1.8 V nominal supply rails commonly used in automotive MCUs, DSPs, and FPGAs — the reset asserts at roughly 93 % of the nominal rail, giving early warning of a brownout before the core logic starts glitching.
