STM6520 is a dual push-button Smart Reset™ with push-button controlled output delay.
The STM6520 is a dual push-button Smart Reset device designed to ensure system stability by filtering inadvertent short reset push-button closures. It implements extended Smart Reset input delay time (tgac) and combined push-button inputs to discriminate between software interrupts and hard system resets. The device features two reset outputs: RST1 (active-low, open-drain) and RST2 (active-high, push-pull).
