STMICROELECTRONICS STGAP4STR Gate Driver, 1 Channels, Isolated, IGBT, SiC MOSFET, 36 Pins, WSOIC

STGAP4STR is an automotive advanced isolated gate driver for IGBTs and SiC MOSFETs. It is a galvanically isolated single gate driver for IGBTs and SiC MOSFETs with advanced protection, configuration and diagnostic features. The architecture of the STGAP4S isolates the channel gate driving from the control and the low voltage interface circuitry through true galvanic isolation. The unique output architecture is designed to allow the use of an external MOSFET push-pull stage giving flexibility in terms of current capability dimensioning and easing the use of several power switches in parallel. The 2 pre-driver outputs are characterized by current capability and output voltage swing optimized for that topology and allow the use of a negative gate driving supply. Applications include inverters for EV/HEV, 600/1200V industrial inverters, EV charging stations, UPS equipment, AC/AC converters, DC/DC converters, solar inverters.
