NCV7517B: MOSFET Pre-Driver, Hex, Low-Side

Description: The NCV7517B programmable six channel low-side MOS...
  • The NCV7517B 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. It features programmable fault management modes and allows power-limiting PWM operation with programmable refresh time. The device offers 3.3 V/5.0 V compatible inputs and the serial output driver can be powered from either 3.3 V or 5.0 V. Power-on reset provides controlled powerup and two enable inputs allow all outputs 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 four discrete internal ratio values. The ratio values are SPI selectable and allow different detection thresholds for each group of three output channels.

    Fault information for each channel is 2-bit encoded by fault type and is available through SPI communication. Fault recovery operation for each channel is programmable and may be selected for latch-off or automatic retry.

    The FLEXMOS family of products offers application scalability through choice of external MOSFETs.
