The NCV7520 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 poweredfrom 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 foreach 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.

The NCV75215 ASSP is intended to operate with a piezoelectric ultrasonic transducer to provide time-of-flight measurement of an obstacle distance during vehicle parking. The high-sensitivity, low-noise operation allows detection from 0.25 m up to 4.5 m for a standard 75 mm pole. The device drives the ultrasonic transducer with a programmable frequency via a transformer. The received echo is amplified and converted to a digital signal, filtered, detected and the magnitude is compared to a time-dependent threshold which is stored in an internal RAM. A bidirectional I/O Line is used to communicate with a master (ECU). The master issues I/O Line commands to the NCV75215 and data are reported back via the same line.

The NCV7535 is a monolithic SPI controlled H-bridge pre-driver providing control of a DC-motor. Thanks to the SPI interface, it includes enhanced feature set useful in automotive systems. This allows a highly integrated solution.

The NCV7546 programmable six channel half−bridge MOSFET pre−driver is one of a family of FLEXMOS automotive grade products for driving logic−level NMOS FETs. The product is controllable by a combination of serial SPI and CMOS−compatible parallel inputs. The pre-driver offers advanced control and protection of the MOSFET. The device and application diagnostic data is communicated via SPI.

The NCV7547 programmable seven channel half−bridge MOSFET pre−driver is one of a family of FLEXMOS automotive grade products for driving logic−level NMOS FETs. The product is controllable by a combination of serial SPI and CMOS−compatible parallel inputs. The pre-driver offers advanced control and protection of the MOSFET. The device and application diagnostic data is communicated via SPI.

The NCV7680 consists of eight linear programmable constant current sources. The part is designed for use in the regulation and control of LED based Rear Combination Lamps for automotive applications. System design with the NCV7680 allows for two brightness levels, one for stop and one for tail illumination, or optional PWM control can also be implemented.Discrete LED brightness levels are easily programmed (stop current value, tail duty cycle value) optional external ballast FET allows for power distribution on designs requiring high currents. Set back power limit reduces the drive current during overvoltage conditions. This is most useful for low current applications when no external FET is used.

The NCV7681 consists of eight 100 mA linear programmable constant current sources. The part is designed for use in the regulation and control of LED based Rear Combination Lamps and blinking functions for automotive applications. System design with the NCV7681 allows for two programmed levels for stop (100% Duty Cycle) and tail illumination (programmable Duty Cycle), or anoptional external PWM control can be implemented. LED brightness levels are easily programmed (stop is programmed to the absolute current value, tail is programmed to the duty cycle) with two external resistors. The use of an optional external ballast FET allows for power distribution on designs requiring high currents. Set back power limit reduces the drive current during overvoltage conditions. This is most useful for low power applications when no external FET is used. The device is available in a SOIC−16 WB package with exposed pad.
