Overview
The STM6519ALARUB6F, 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 ideal for various electronic applications. The STM6519 operates over a broad voltage range from 2.0 V to 5.5 V and features low supply current, integrated test mode, and a single Smart Reset input with adjustable delay times.

Q & A
- What is the operating voltage range of the STM6519ALARUB6F?
The operating voltage range is from 2.0 V to 5.5 V.
- What is the typical supply current of the STM6519ALARUB6F?
The typical supply current is 1 μA.
- How is the reset pulse duration controlled in the STM6519ALARUB6F?
The reset pulse duration can be either fully push-button controlled or defined by a factory-programmed output reset pulse duration (tREC).
- What are the options for the reset output of the STM6519ALARUB6F?
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 STM6519ALARUB6F?
The operating temperature range is from -40 °C to 85 °C.
- What package type is the STM6519ALARUB6F available in?
The device is available in a UDFN6 package, measuring 1.00 mm x 1.45 mm.
- Is the STM6519ALARUB6F RoHS compliant?
- How does the integrated test mode work in the STM6519ALARUB6F?
The device enters test mode by pulling the SR input up to VTEST (VCC + 1.4 V) or above, allowing for quick testing without repeating test mode triggering.
- What are some common applications of the STM6519ALARUB6F?
- What is the significance of the Smart Reset delay (tSRC) in the STM6519ALARUB6F?
The Smart Reset delay (tSRC) ensures that the reset output is asserted only after the SR input is held active for the selected delay time, preventing inadvertent resets.
