NCV7519, NCV7519A
FLEXMOS] Hex Low-side
MOSFET Pre-driver
The NCV7519/A 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.
