The NCV7520 Programmable Six-Channel Low-Side MOSFET Pre-Driver is a FLEXMOS automotive grade product family for driving logic level MOSFETs. The product can be controlled through a combination of serial SPI and parallel inputs. The device provides 3.3-V/5-V compatible inputs and the serial output driver can be powered from either 3.3-V or 5-V. A reset input allows external reinitialization, and an enable input allows all outputs and diagnostics to be disabled simultaneously. Each channel independently monitors the drain voltage of its external MOSFET for fault conditions. The shorted load fault detection threshold is fully programmable using a combination of an externally programmed reference voltage and a discrete internal ratio. These ratios are SPI selectable, allowing different detection thresholds to be set for each channel. Fault recovery for each channel allows programmable, selectable latching shutdown or automatic retry. The status information for each channel is 3 bits coded for the fault type, provided via SPI communication. The FLEXMOS family offers application scalability through selection of external MOSFETs.
