NCV7748 Automotive LIN Low-Side Relay Driver The NCV7748 is an automotive eight channel lowside driver providing drive capability up to 0.75 A per channel. Output control is via a LIN bus with optimized LIN command set allowing high flexibility while still maintaining compliance to SAE J2602 LIN www.onsemi.com specification. Each output driver includes an output clamp for inductive loads. MARKING All output drivers have overcurrent detection implemented. DIAGRAM Selected low side drivers (OUT4,8) offer additional reporting of faults 14 14 for open load (or short to ground) and individual over temperature 1 conditions which allows connection to a wiring harness outside of the NCV7748G SOIC14 module. AWLYWW D2 SUFFIX The NCV7748 is available in an SOIC14 package.
