Reset supervisor for 3.3V and 2.5V rails
The TPS3705-30DR: It is the part to reach for when you need a clean, glitch-free reset on a 3.3V or 2.5V processor or FPGA supply — the 2.63V threshold sits well below the nominal rail but above the brownout zone, so it catches dips before the logic loses state. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor, which saves a component and simplifies the BOM for high-density boards.
140 ms reset timeout — what it buys you
That is the window the datasheet guarantees — the actual timeout is typically longer, but nominal is not absolute max, so budget the minimum when sizing the power-good sequence. The 140 ms minimum reset timeout provides margin for a typical power-up ramp.
