Active-Semi delivers the industry's most integrated motor control solutions for
floor care vacuum pumps, scrubbers, and drivetrain motors transitioning from
brushed to BLDC and high-voltage permanent magnet motors. 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.

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.
