Description
NCV7518
FLEXMOS] Hex Low‐side MOSFET Pre‐driver
The NCV7518 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.
