BYD Semiconductor's new power device driver chip independent research and development is complete! Mass delivery was realized in December

On December 14, BYD Semiconductor officially announced that it has successfully independently developed and mass-produced 1200V power device driver chip - BF1181, and achieved mass supply to major manufacturers in December this year.

According to reports, BF1181 is a magnetic isolation single-channel gate driver chip, used to drive 1200V power devices, while having excellent dynamic performance and working stability, and integrated a variety of functions, such as fault alarm, active Miller clamp, primary and secondary undervoltage protection and so on.

The BF1181 also integrates analog level detection for temperature or voltage detection and improves chip versatility, further simplifying system design such as size and cost.

In order to safely and reliably use the power device, and to realize the real-time control of the MCU's low-voltage drive signal to control the opening and shutdown of the power device, the power device driver chip is indispensable, it integrates the drive function and various protection functions in one. It can be said that every power device needs a driver chip – the right driver chip can make power electronics systems more effective with less.

In fact, China's automotive power device driver chip currently mainly relies on imports, before the domestic basically did not meet the application of the car grade high-voltage power device driver chip.

In 2011, BYD Semiconductor successfully developed a 600V power device driver chip, which was applied to intelligent power module products in batches and widely used in the field of inverter home appliances.

The self-developed 1200V driver chip BF1181 has a wider range of applications and can be applied to EV/HEV power modules, industrial motor control drives, industrial power supplies, solar inverters and other fields.

Prior to this, the power device driver chip was easy to ignore because of its small single value, which accounted for a relatively low proportion of the cost of the automotive electronic system, but it was on a par with the power device in the automotive electronic system and played a vital role in new energy vehicles.

The successful research and development of BF1181 and the batch supply are a significant leap in both quality control and technological development, which has promoted BYD Semiconductor to take a solid step in the field of power device driver chips.

In addition, BYD Semiconductor has also realized the independent controllability of the core technologies of key products, greatly driving the upstream and downstream industrial chains and sharing results, promoting the development of key components and components of new energy vehicles, and ultimately promoting the rapid development of the new energy automobile industry.
