NCV7751
Twelve Low-Side Relay
Drivers
The NCV7751 is an automotive grade twelve channel low−side
driver providing drive capability up to 600 mA per channel. Output
control is via a SPI communication and offers convenient reporting of
faults for open load (or short to ground), over load, and over
temperature conditions. Additionally, all the drivers have integrated
output clamps for inductive loads.
The NCV7751 is available in a SSOP−24 exposed pad package for
optimal thermal performance.

3. Reduced performance down to 4 V provided VDDA is not in Power−On Reset.
4. Each output driver is protected by its’ own individual thermal sensor.
5. Input signals H→L→H greater than 50usec are guaranteed to be detected.
