Acve-Semi delivers the industry's most integrated motor control soluons for

ﬂoor care vacuum pumps, scrubbers, and drivetrain motors transioning from

brushed to BLDC and high-voltage permanent magnet motors. The PAC™

architecture delivers a premium one-chip soluon with best-in-class ﬁrmware.

BRUSHLESS ADVANTAGES: Increase eﬃciency, life,

range and max speed, and power, by transioning to

BLDC motors while decreasing heat dissipaon,

maintenance costs, and electrical and audible noise.

Mid-Voltage BLDC and 600V PMSM Drive Solutions for

Floor Care using Active-Semi's Power Application Controller

(PAC™) IC Family

PAC™ Architecture Summary

SUPPORT: Acve-Semi is a global

company with world-wide sales oﬃces

with applicaon engineering support,

global distribuon, and Independent

Design House (IDH) partnerships around

the globe. Jump start development with

our evaluaon kits, reference designs,

schemacs, example code, and soware

development kit (SDK) for PAC™

BOM & FOOTPRINT REDUCTION: The PAC™ architecture reduces PCB

footprint, component count, and total BOM cost over alternate soluons.

The advantages apply to both 600V boards that ulize an expensive IPM or

discrete gate drivers and DC powered boards where the MMPM and 70V

capabilies oﬀer wide input voltage and headroom to reduce power conversion

and protecon circuitry.

FIRMWARE PERFORMANCE: Acve-Semi's high-quality ﬁrmware IP and control

GUI soware reduces development me and me-to-market while providing

rich beneﬁts such as Acve 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. Acve-Semi delivers

ludicrous speed. back-EMF operang up to 30,000 RPM with two pole pairs.
