Recently, from BYD Semiconductor officials learned that its recent independent research and development based on the previous research and development results, successfully independently developed and mass-produced 1200V power device driver chip - BF1181, in December this year to achieve mass supply to major manufacturers.
It is understood that BF1181 is a magnetically isolated single-channel gate driver chip for driving 1200V power devices, compatible with 1200V IGBT and SiC. The product can be widely used in EV/HEV power modules, industrial motor control drives, industrial power supplies, solar inverters and other fields.
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 power device on and off, the power device driver chip is indispensable. At present, in the motor drive of new energy vehicles, vehicle air conditioning frequency conversion and heating, automotive steering power system and other fields, it is necessary to use power devices to drive chips. The successful research and development of BF1181 by BYD Semiconductor undoubtedly plays an important role in promoting the development of new energy vehicles in China.
