onsemi NCV7547 FLEXMOS™ Half-Bridge MOSFET Pre-Driver

onsemi NCV7547 FLEXMOS™ Half-Bridge MOSFET Pre-Driver is a 7-channel, programmable, and automotive-grade device suitable for driving logic-level NMOS FETs. This pre-driver is controllable by a combination of serial SPI and CMOS-compatible parallel inputs. NCV7547 supports an integrated charge pump for high-side gate drive and switched reverse battery protection. This pre-driver employs internal power-on reset and offers controlled power-up.
