At 2.64V, the supervisor asserts reset with a guaranteed minimum 120ms timeout, giving the supply time to recover or the system time for an orderly shutdown. For a 3.3V rail with ±5% tolerance, the lowest valid voltage is 3.135V, so the 2.64V trip point provides roughly 0.5V of margin before the reset fires — adequate for most automotive ECU power designs. For a tier-one ECU program, the AEC-Q100 cert is the minimum gate — this part clears it without a PPAP waiver.","metaTitle":"TPS3809L30QDBVRQ1 Simple Reset/Power-On Reset, AEC-Q100","metaDescription":"Texas Instruments TPS3809L30QDBVRQ1 automotive Simple Reset/Power-On Reset IC.
