That number tells you which supply rail this supervisor watches: it sits below a nominal 3.3V rail (which would trigger a reset at about 2.93V for a typical 3.3V supervisor) but above a 2.5V rail. If your design runs a 3.3V core and you need the reset to assert before the logic enters the brownout region, the 2.64V threshold catches the droop early enough to hold the microcontroller in reset while the rail recovers. The 130ms minimum reset timeout holds the output low long enough for the supply to stabilise after power-up — the downstream processor sees a clean release, not a glitch on the reset line as the rail rings. ## Open-drain output — wired-OR flexibility with a pull-up cost The output is open-drain, active low. That means the supervisor can only pull the reset line low; it cannot drive it high. You must add an external pull-up resistor to the logic supply — typically 10 kΩ to 100 kΩ — so that when the reset releases, the line floats high through the resistor. The trade-off is that multiple open-drain outputs (watchdog, other supervisors) can share the same reset line in a wired-OR configuration, which saves a GPIO on the processor. The SOT-23-3 package has a junction-to-ambient thermal resistance around 200°C/W, so the total dissipation from the pull-up current and the leakage across the open-drain FET stays under the thermal budget across the full range.","metaTitle":"Texas Instruments TLV803EA26DBZR Supervisor, 2.64V Threshold","metaDescription":"Active Texas Instruments TLV803EA26DBZR simple reset/power-on reset IC, 2.64V threshold, 130ms timeout, open-drain output, -40°C to 125°C.
