The SA110 is Apex Microtechnology’s first high current, high voltage half H-bridge to utilize Sili-con Carbide (SiC) MOSFETs with integrated gate drive. SiC MOSFETs provide a reduction in power loss compared to the more commonly used silicon or IGBT options. Benefits include reduced switching losses, lower conduction losses, and a low dependency of RDS(on) over temperature.
The SA110 features integrated gate drive and control logic, a very high 400 kHz MAX switching frequency, and 28 A of continuous output current in the A grade variant. This hybrid is offered in a 12-pin PSIP package to provide a compact footprint and is designed with under-voltage lock-out and active Miller clamping protection features. With integration of the gate drive, switching behavior speeds are improved as parasitic impacts are reduced and easier to control. Silicon Carbide, along with the integrated gate drive, make SA110 the best choice for solutions where focus is on over temperature performance, high efficiency, and compact design.
Designers can use the SA110 for applications in industrial, avionics, and military market segments. Example applications include sonar, brushless DC motor drivers, and DC/AC inverters.
