NCV7520 FLEXMOS Hex Low-side MOSFET Pre-driver The NCV7520 programmable six channel lowside MOSFET predriver is one of a family of FLEXMOS automotive grade products for driving logiclevel MOSFETs. The product is controllable by a www.onsemi.com 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 poweron reset provides MARKING controlled power up. A reset input allows external reinitialization and DIAGRAMS an enable input allows all outputs and diagnostics to be simultaneously 1 disabled. QFN32 NCV7520 Each channel independently monitors its external MOSFETs drain MW SUFFIX AWLYYWW voltage for fault conditions. Shorted load fault detection thresholds are CASE 485CZ 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. TQFP32 EP NCV7520 Fault recovery operation for each channel is programmable and may FP SUFFIX AWLYYWW be selected for latchoff or automatic retry. Status information for CASE 136AB each channel is 3bit encoded by fault type and is available through SPI communication. The FLEXMOS family of products offers application scalability A = Assembly Location through choice of external MOSFETs.
