Active-Semi, Inc. has expanded its Power Application Controller-based BLDC motor control portfolio, adding the PAC5223 IC, four development kits and firmware solutions. The company claims that the addition delivers industry-leading performance with the lowest system-cost solution available for 3-phase brushless DC (BLDC) motors for up to 72V.
In addition, the development boards and firmware for sensorless Trapezoidal and field-oriented control (FOC) reduce development costs and spur rapid prototyping for a variety of applications — including power tools, garden tools, drones, radio controlled cars, and general-purpose BLDC applications.
“PAC5223 IC’s high level of integration including 72V gate drivers for 3-phase control, multi-mode power manager, configurable analog front-end, embedded ARM Cortex core coupled with Active-Semi’s Total Hibernate Mode and other patented features, delivers the smallest system design at the highest system efficiency,” says David Briggs, vice-president and general manager at Active-Semi. “We are excited about the rapidly expanding customer base that is now ramping into production with PAC5223.”
The small 6mm x 6mm QFN package, houses many features for added customer value. Input power less than 20V connects directly to PAC5223 while applications with input up to 72V can use the onboard buck controller, reducing system BOM. Four onboard LDOs simplify system power management.
The EP-HYDRA-X23-1 and EP-HYDRA-X23S-1 extend the family of HYDRA-X evaluation kits to enable fast prototyping with the PAC5223 IC. Also, the EH-BLDCM1-1 and EH-FOC1-1 HYDRA-X heads along with Active-Semi’s motor control firmware and tuning software simplify system development with sensored and sensorless FOC and sensorless Trapezoidal motor control applications.
Reference designs with footprints as small as 2mm x 3mm for full-fledged 3-phase FOC based motor control up to 72V are available.
