The NCV7518 / NCV7518A programmable six channel low-side

MOSFET pre-driver is one of a family of FLEXMOS automotive

grade products for driving logic-level MOSFETs. The product is

controllable by a combination of serial SPI and parallel inputs. The

device offers 3.3 V/ 5 V compatible inputs and the serial output driver

can be powered from either 3.3 V or 5 V. An internal power-on reset

provides controlled power up. A reset input allows external

re-initialization and an enable input allows all outputs and diagnostics

to be simultaneously disabled.

Each channel independently monitors its external MOSFET’s drain

voltage for fault conditions. Shorted load fault detection thresholds are

fully programmable using an externally programmed reference

voltage and a combination of discrete internal ratio values. The ratio

values are SPI selectable and allow different detection thresholds for

each channel.

Fault recovery operation for each channel is programmable and may

be selected for latch-off or automatic retry. Status information for each

channel is 3-bit encoded by fault type and is available through SPI

communication.

The FLEXMOS family of products offers application scalability

through choice of external MOSFETs.
