UnitedSIC deal drives Qorvo into automotive
RF chip maker Qorvo is to integrate its recent silicon carbide acquisition to boost its position in the booming electric car market, the key players tell Nick Flaherty

Qorvo's acqusition of UnitedSiC announced earlier this week will  see UnitedSiC become part of Qorvo’s Infrastructure & Defense Products (IDP) business alongside its 2019 acquisition of power management chip designer Active Semiconductor.

While there are clear advantages in using the UnitedSiC devices in power designs for telecoms applications alongside Qorvo’s RF devices as well as existing data centre power supply designs, the deal opens up the automotive market for Qorvo.

“We view this as very complementary,” said Chris Dries, former CEO and founder of UnitedSiC (above left) who is staying with Qorvo as general manager of Power Device Solutions tells eeNews Europe. “One of the things I loved about this deal is everyone has a home, there’ s no redundancy in personel.”

The Active Semi business is key to this deal. “We were brought in in 2019 and we have been able to expand beyond consumer into industrial and defence applications so the combination of United helps us push into more automotive applications much faster,” said David Briggs, senior director programable power management at Qorvo and former CEO at Active Semi (above right). “The technology is there from a control perspective and this opens up the opportunity to apply our innovative algorithms to automotive.”

“This will allow traction inverters with sophisticated control and lowest RDS on with the JFET cascodes to really exploit areas of functional safety,” said Dries. “We have a number of design sin the US and Europe all using our discrete TO47 devices both 400V with the 750V devices with the 5.9mO devices and 800V with 1200V class devices.”
