FAQs

Q: Is this IC suitable for 12V automotive systems?
A: Yes, its 42V load voltage rating exceeds standard 12V/24V automotive requirements with margin.

Q: Does it require external heat sinks?
A: Typically not – the 165mΩ Rds(on) minimizes heat generation, and over-temperature protection safeguards operation.

Q: What does AEC-Q100 qualification mean?
A: This indicates rigorous testing for automotive stress tolerance, including temperature cycling, vibration, and humidity resistance.

Q: Can I parallel channels for higher current?
A: Yes, dual channels can be paralleled to support up to 4A continuous current.

Q: How does auto-restart function work?
A: After tripping due to faults, the IC automatically attempts recovery once conditions normalize.

Q: Where can I find the datasheet?
A: Download full specifications from the datasheet section on this product page at PCXCo.com.
