SAN FRANCISCO--Chip and component supplier Littelfuse Inc. has acquired a majority stake in Monolith Semiconductor Inc., a Texas-based that is developing high-voltage silicon carbide power diodes and switches.
Littelfuse (Chicago) accumulated a majority position in the startup after making an incremental $15 million investment this week, according to the company. Littelfuse said it would begin including Monolith in its operating results.
It was not immediately known what Littelfuse's total investment in Monolith has been to date. The company initially announced in 2015 that it invested an undisclosed amount in Monolith.
Littelfuse was drawn to Monolith due to its experience with silicon carbide, an emerging semiconductor material that enables power devices to operate at higher switching frequencies versus conventional silicon. This allows inverters and motor drives to operate with improved energy efficiency and reduced system cost, according to Littelfuse.
“With the increasing needs to make power electronic devices that will be stronger and more efficient, we are excited about the opportunities this game-changing technology provides,” said Ian Highley, Littelfuse's chief technology officer, in a press statement.
Sujit Banerjee, Monolith CEO, said the company’s relationship with Littelfuse has helped it move closer to commercializing its silicon carbide technology. “We are working closely with Littelfuse to position our combined portfolios to develop innovative solutions for our customers,” Banerjee added.
