NCV7547 FLEXMOS 7x Half-bridge MOSFET Pre-driver The NCV7547 programmable seven channel halfbridge MOSFET predriver is one of a family of FLEXMOS automotive grade products for driving logiclevel NMOS FETs. The product is controllable by a www.onsemi.com combination of serial SPI and CMOScompatible parallel inputs. An internal poweron reset provides controlled power up. A reset input allows external reinitialization and a failsafe input allows the device to be safely disabled in the event of system upset. Each channel independently monitors its external MOSFETs drain source voltages for fault conditions. Overload detection thresholds are SPI selectable and the product allows different 148 detection thresholds for each channel. QFNW48 The FLEXMOS family of products offers application scalability 7x7, 0.5P CASE 484AJ through choice of external MOSFETs.
