The reset output remains low for a minimum of 15 ms after the supply recovers, providing a clean power-on-reset signal to the downstream MCU or SoC.
The SOT-23-5 package (SC-74A, SOT-753) is a standard surface-mount footprint compatible with automated assembly lines.
The reset timeout is 15 ms minimum. After the monitored voltage rises above the 4.55 V threshold, the reset output stays low for at least 15 ms before releasing, ensuring the system power supply and oscillator have stabilised.
Yes, the part is AEC-Q100 qualified, as indicated by the 'Q1' suffix in the order code. This qualifies it for automotive applications including under-hood and cabin environments.
