That minimum guarantees the 2.5V rail has fully settled and the oscillator has started before the processor is released from reset — a common failure point when the timeout is too short for the bulk capacitance on the rail.","metaTitle":"TI TPS3851G25EDRBR Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3851G25EDRBR simple reset/power-on reset IC.
