Overview
The STM6519APARUB6F, produced by STMicroelectronics, is a single-pin, push-button Smart Reset device designed to provide reliable and glitch-immune reset functionality. This device ensures that inadvertent short reset push-button closures do not cause system resets, making it suitable for various applications requiring robust reset mechanisms.

Q & A
- What is the operating voltage range of the STM6519APARUB6F?
The operating voltage range is from 2.0 V to 5.5 V.
- What is the typical supply current of the STM6519APARUB6F?
The typical supply current is 1 μA.
- How does the Smart Reset delay (tSRC) work?
The Smart Reset delay (tSRC) ranges from 0.5 s to 10 s in 0.5 s steps, and the reset output is asserted after the Smart Reset input is held active for the selected tSRC delay time.
- What are the options for the reset pulse duration (tREC)?
The reset pulse duration can be either fully push-button controlled with no fixed or minimum pulse width guaranteed, or defined with a factory-programmed duration (tREC).
- What types of reset outputs are available?
The reset output can be active-low or active-high, and it can be configured as push-pull or open drain with an optional pull-up resistor.
- What is the operating temperature range of the STM6519APARUB6F?
The operating temperature range is from -40 °C to 85 °C.
- What package type is the STM6519APARUB6F available in?
The device is available in a UFDFPN 1x1.45x0.6 6L PITCH0.5 package.
- Is the STM6519APARUB6F RoHS compliant?
- How does the integrated test mode work?
The integrated test mode allows for easy testing by pulling the SR input up to VTEST (VCC + 1.4 V) or above, which triggers a shortened tSRC-INI and provides user feedback regarding entry into test mode.
- What are some common applications of the STM6519APARUB6F?
