Frequently Asked Questions

What input voltage range does the LM66100QDCKRQ1 support?

The LM66100QDCKRQ1 operates across a 1.5 V to 5.5 V input range and provides single-channel input fault protection, functioning as an ideal-diode controller for reverse-polarity and overvoltage handling in automotive power paths.

Why is the LM66100QDCKRQ1 suited to automotive power-path designs?

The LM66100QDCKRQ1 carries TI's -Q1 automotive qualification (AEC-Q100), and its 6-pin SOT23 package combined with a 1.5 V to 5.5 V operating range suits compact automotive fault-protection circuits requiring reliable low-voltage operation.

How compact is the LM66100QDCKRQ1 package footprint?

The LM66100QDCKRQ1 ships in a 6-pin SOT23 package, a small outline footprint that supports single-channel ideal-diode protection across a 1.5 V to 5.5 V input range in space-constrained automotive control modules.

Which systems use the LM66100QDCKRQ1 for power-path protection?

Body-control modules, infotainment head units, and other automotive electronics use the LM66100QDCKRQ1 to guard a single 1.5 V to 5.5 V input channel against reverse-battery faults without the voltage drop penalty of a Schottky diode.
