Product Overview
NCV7240: 8 Channel Low-Side Relay Driver
For complete documentation, see the data sheet
Product Description
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 thru OUT4 while disabling OUT5 thru OUT8. Each output driver is protected for over load current and includes an output
clamp for inductive loads. The NCV7240 is available in a SSOP24 fused lead package.
