Q & A
- What is the operating voltage range of the STM6519APBBUB6F?
The operating voltage range is from 2.0 V to 5.5 V.
- What is the typical supply current of the STM6519APBBUB6F?
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 or defined by a factory-programmed tREC option.
- What are the available configurations for the reset output?
The reset output can be configured as active-low or active-high, and as push-pull or open drain with an optional pull-up resistor.
- What is the operating temperature range of the STM6519APBBUB6F?
The operating temperature range is from -40 °C to 85 °C.
- What package type is the STM6519APBBUB6F available in?
The device is available in a UDFN6 package (1.00 mm x 1.45 mm).
- Is the STM6519APBBUB6F RoHS compliant?
Yes, the device is RoHS compliant and Halogen-Free, classified under Ecopack3.
- 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.
- What are some common applications of the STM6519APBBUB6F?
Common applications include mobile phones, smartphones, PDAs, and industrial applications requiring robust reset mechanisms.
