NCV7748 Datasheet, PDF (1/30 Pages) ON Semiconductor – Automotive LIN Low-Side Relay Driver

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 command set allowing high
flexibility while still maintaining compliance 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.
