The pinout is standard: GND, RESET, VDD. The 4.55V threshold is set for monitoring a 5V rail — it asserts reset when the supply falls to approximately 4.55V, which is typical for 5V logic families. The 120ms timeout is long enough to cover most power-supply ramp-up times without needing an external capacitor.","metaTitle":"TI TPS3809I50MDBVREP Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3809I50MDBVREP Simple Reset/Power-On Reset IC.
