NXP Semiconductors GD3160 Advanced Gate Drivers
NXP Semiconductors GD3160 Advanced Gate Drivers are designed to drive SiC and IGBT modules for xEV traction inverters, OBC, and DC-DC converters. The GD3160 features integrated galvanic isolation, a programmable interface via SPI, and advanced programmable protection options, such as overtemperature, desaturation, and current sense protection.
The NXP Semiconductors GD3160 Advanced Gate Drivers capably drive SiC MOSFETs and IGBT gates directly utilizing high-performance switching, low dynamic on-resistance, and rail-to-rail gate voltage control.
The GD3160 autonomously manages faults, reporting power device and gate driver status via the INTA and INTB pins and the SPI interface. GD3160 includes self-test, control, and protection functions for designing high-reliability systems (ASIL C/D) and meets the stringent requirements of automotive applications, fully AEC-Q100 grade 1 qualified.
