概览

The NCP81080 is a high performance dual mosfet (high side and low side) gate-drive IC designed for driving MOSFETs operating up to 180 V. The NCP81080 integrates a driver IC and a bootstrap diode and offers 0.5A source/0.8A sink driving capability. Anti-cross conduction circuit is integrated to prevent shoot through issues. The high side and low side drivers are independently controlled.This driver is ideally suited for use in high voltage buck and motor control applications.The part is offered in a SO8 and 8 pin 2mm by 2mm DFN package and fully specified from -40C to 140C.
