The 130ms minimum reset timeout holds the processor in reset long enough for the supply to stabilize after a power-up or a glitch, which is the standard window for most MCU boot sequences. ## Active-low open-drain output — wiring it into the system The reset output is active-low and open-drain, so it pulls the reset line low when the voltage drops below threshold. You need an external pull-up resistor to Vdd (typically 10 kΩ to 100 kΩ) to hold the line high during normal operation. Open-drain also means multiple reset outputs can be wire-ORed together — useful if you have several supervisors feeding into one MCU reset pin. ## Industrial temperature range and package The SOT-23-3 package (TO-236, SC-59 compatible) is a standard three-pin footprint that fits into tight layouts without consuming board space. Surface-mount assembly with standard reflow profiles; no special handling beyond the usual MSL precautions.","metaTitle":"TI TLV803EA43VDBZR Simple Reset IC, 4.38V Threshold","metaDescription":"Texas Instruments TLV803EA43VDBZR active-low open-drain reset IC with 4.38V threshold and 130ms timeout.
