Reset stays asserted for a minimum of 65 ms after the rail returns above threshold, giving the system oscillator and core logic time to stabilise. ## Open-drain output — plan the pull-up Because the output is open drain, the reset signal is actively pulled low but relies on an external resistor to pull it high when the condition clears. Pick the pull-up value so the rise time stays within the downstream reset input's requirements — a 10 kΩ resistor to the rail is a common starting point. The active-low polarity means the reset line is held low during power-up, brown-out, and manual reset events. ## Single-voltage monitor, SOT-23-6 footprint This part monitors one voltage rail — no multi-channel sequencing here. The SOT-23-6 package is a small, surface-mount footprint that fits on tight boards and is straightforward to hand-solder or reflow.","metaTitle":"TI TPS3103K33DBVR Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3103K33DBVR Simple Reset/Power-On Reset IC with 2.941V threshold, 65ms min timeout, open-drain active-low output.
