Allegro MicroSystems announced an expansion of its Power-Thru isolated gate driver portfolio with a new chipset designed for high-voltage silicon carbide (SiC) applications. The AHV85003/AHV85043 chipset complements the company’s flagship integrated AHV85311, forming a complete SiC ecosystem for AI data centers, electric vehicles, and clean energy systems. The expanded lineup simplifies power-conversion design by eliminating the need for external isolated bias supplies.
Allegro’s Power-Thru technology delivers signal and power across a single isolation barrier, reducing common-mode capacitance by up to 15x and improving electromagnetic interference performance by as much as 20 dB, addressing a key noise challenge in high-voltage systems.
The company also introduced the ACS37200, a galvanically isolated current sensor with 50 µΩ conductor resistance, which it says cuts power loss by 90% versus traditional shunt resistors and reduces system size by up to 95%.
