Product details

The TPS3809J25DBVT: That minimum timeout window gives the rest of the system time to stabilize before the processor or FPGA starts executing code. The output is push-pull, totem pole, active-low — it drives the reset pin directly without needing an external pull-up resistor. This matters when you are swapping a supervisor on site: fewer parts to check, less chance of a floating pin causing a no-boot condition.

Package and field-fit

Housed in a SOT-23-3 (TO-236, SC-59) surface-mount package, the TPS3809J25DBVT takes up minimal board area and can be replaced with a standard soldering iron and some flux — no hot-air station required if the pads are accessible. The three pins are laid out clearly: ground, reset output, and supply input; orientation is unambiguous once the package is on the board. If the board lives in a controlled indoor space, this is more than enough margin.

Frequently asked questions

Will TPS3809J25DBVT drop into a board that was specified around TL7702BID without rewiring?

Not directly. The TL7702BID uses an open-drain output that requires an external pull-up resistor, while the TPS3809J25DBVT has a push-pull output that drives the reset line directly. The TL7702BID also lacks a built-in reset timeout — it responds with a 270ns typical propagation delay rather than a 120ms minimum delay. The package and pinout differ as well, so a board spin or at least a layout change is needed.

What compliance documentation does Texas Instruments provide for TPS3809J25DBVT?

The TPS3809J25DBVT is ROHS3 compliant per Texas Instruments' lifecycle record. Standard documentation includes the datasheet, RoHS declaration, and material composition data available through TI's product page.
