NCV7517B FLEXMOS MOSFET Pre- Driver, Hex, Low-Side The NCV7517B programmable six channel lowside MOSFET pre TM driver is one of a family of FLEXMOS automotive grade products for driving logiclevel MOSFETs. The product is controllable by a combination of serial SPI and parallel inputs. It www.onsemi.com features programmable fault management modes and allows power limiting PWM operation with programmable refresh time. The MARKING DIAGRAM 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. Poweron reset provides controlled powerup and two enable inputs allow all outputs LQFP32 to be simultaneously disabled. NCV7517B FT SUFFIX Each channel independently monitors its external MOSFETs AWLYYWWG CASE 561AB 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 A = Assembly Location values. The ratio values are SPI selectable and allow different WL = Wafer Lot detection thresholds for each group of three output channels. YY = Year WW = Work Week Fault information for each channel is 2bit encoded by fault type G = PbFree Package and is available through SPI communication. Fault recovery operation for each channel is programmable and may be selected for latchoff or automatic retry. ORDERING INFORMATION The FLEXMOS family of products offers application scalability Device Package Shipping through choice of external MOSFETs.
