The PAC™ architecture delivers a premium one-chip solution with best-in-class firmware. BRUSHLESS ADVANTAGES: Increase efficiency, life, range and max speed, and power, by transitioning to BLDC motors while decreasing heat dissipation, maintenance costs, and electrical and audible noise. Featured Products and Firmware PAC5223 6x6mm PAC™ IC w/ 70V gate drivers for sensored or sensorless BLDC motors PAC5253 8x8mm PAC™ IC w/ 600V gate drivers for high-voltage PMSM motors Active WhisperDrive™ Field oriented control (FOC) algorithm for higher efficiency, low torque ripple, and quiet operation High-Speed Back-EMF Trapezoidal drive at 2 kHz electrical frequency About Active-Semi Headquartered in Dallas, Texas, USA Founded in 2004 Investors: LG, USVP and Tenaya Capital 1.5 Billion ICs shipped Shipping over 30M ICs per Quarter Operations in the US, Europe, China, Taiwan, Hong Kong, Japan and S Korea ISO 9001:2008 Company www.active-semi.com/about/leadership Active-Semi International, Inc. One Allen Center 700 Central Expressway South, Ste. 330 Allen, TX 75013 USA BOM & FOOTPRINT REDUCTION: The PAC™ architecture reduces PCB footprint, component count, and total BOM cost over alternate solutions. The advantages apply to both 600V boards that utilize an expensive IPM or discrete gate drivers and DC powered boards where the MMPM and 70V capabilities offer wide input voltage and headroom to reduce power conversion and protection circuitry. FIRMWARE PERFORMANCE: Active-Semi's high-quality firmware IP and control GUI software reduces development time and time-to-market while providing rich benefits such as Active WhisperDrive™ FOC to improve efficiency while reducing torque ripple and noise. FOC operates at 1050 Hz today and increasing with field weakening and other techniques. Active-Semi delivers ludicrous speed. back-EMF operating up to 30,000 RPM with two pole pairs. Reference designs demonstrate the following PAC™ firmware capability: • • • • • • 15% Efficiency Gain for BLDC Hall Sensored Firmware Trapazoidal BEMF Sensorless 2 kHz Electrical Frequency BEMF FOC with Speed Estimator 5% Efficiency Gain using FOC SUPPORT: Active-Semi is a global company with world-wide sales offices with application engineering support, global distribution, and Independent Design House (IDH) partnerships around the globe.
