SSOP *24 Symbol Description 1 GND Ground. 2 GND Ground. 3 OUT1 Channel 1 low *side drive output. Requires an external pull *up device for operation. 4 OUT2 Channel 2 low *side drive output. Requires an external pull *up device for operation. 5 OUT3.

NCV7240, NCV7240A, NCV7240B Octal Low-Side Relay Driver The NCV7240 is an automotive eight channel low side driver providing drive capability up to 600 mA per channel. Output control is via a SPI port and offers convenient reporting of faults for open load (or short to ground), over load, and over temperature conditions. Additionally, parallel control of the outputs is addressable (in pairs) via the INx pins. A dedicated limp home mode pin (LHI) enables OUT1 OUT4 while d.
