NCV7748 Datasheet Text
NCV7748
Automotive LIN Low-Side Relay Driver
The NCV7748 is an automotive eight channel low- side driver providing drive capability up to 0.75 A per channel. Output control is via a LIN bus with optimized LIN mand set allowing high flexibility while still maintaining pliance to SAE J2602 LIN specification.
Each output driver includes an output clamp for inductive loads. All output drivers have overcurrent detection implemented. Selected low side drivers (OUT4,8) offer additional reporting of faults for open load (or short to ground) and individual over temperature conditions which allows connection to a wiring harness outside of the module. The NCV7748 is available in an SOIC14 package.
