EPC launches tiny EPC91132 three-phase BLDC motor inverter - Bisinfotech

EPC has launched the EPC91132 three-phase BLDC motor inverter chip, a compact power semiconductor device designed for miniaturized applications. This new semiconductor solution represents significant ... Read original →

EPC’s EPC91132 isn’t just another inverter chip—it’s a strategic GaN incursion into the motor control stack. Its ultra-high switching frequency forces MCU vendors to overhaul PWM architectures and pushes PCB laminates toward low-loss, high-frequency specs, triggering a vertical tech cascade. With U.S. and EU policies tightening on critical electronics supply chains, reliance on non-domestic foundries could expose EPC to export controls, especially for automotive-grade deployments, inflating compliance overhead. Competitors like Infineon and TI will likely fast-track integrated SiC/GaN motor drivers to counter EPC’s lead in sub-kW applications. Within 18 months, this device will accelerate capacitor-less BLDC designs in power tools and industrial servos, rendering legacy IGBT solutions obsolete below 1 kW and resetting efficiency benchmarks across low-voltage motor drives.
