The user-programmable PAC5532 IC along with firmware IP enables
high-performance high-voltage battery-powered BLDC applications with a
150MHz Arm® Cortex®-M4F
with 128kB FLASH to reduce time-to-market using sensored Trapezoidal,
sensorless BEMF or sensorless Field-Oriented Control (FOC) with the same
DALLAS–(BUSINESS WIRE)–Active-Semi Int. Inc. (www.active-semi.com)
announced today a new member of its PAC55XX family of PAC®
high-performance motor controllers with the PAC5532 IC. It is supported
by an Evaluation Kit (EVK) and accompanying firmware for easy and fast
evaluation of advanced motor control solutions.
The new PAC5532 contains the highest-performance MCU found in an
integrated motor control and driver product on the market. It contains a
150MHz Arm® Cortex®-M4F MCU with 128kB FLASH,
32kB SRAM and an integrated Floating Point Unit (FPU) with Digital
Signal Processor (DSP) instructions for highly efficient implementation
of motor control and drive applications. The MCU also contains 4-level
code protection, a cache for high-speed FLASH access, ECC for SRAM data
and a CRC engine.
The PAC5532 also integrates highly-optimized peripherals specifically
designed for 40V to 120V BLDC motor control and drive applications, such
as battery-powered garden and power tools, e-bikes, e-skateboards, and
other medium voltage applications.
The 160V PAC5532 is optimized for battery-powered BLDC applications from
40V to 120V. Integrated with the high-performance MCU is the power
management, gate drivers and signal-conditioning for 3-phase inverter
applications. The PAC5532 contains a 160V DC/DC Buck controller and a
5V, 200mA DC/DC Converter. The PAC5532 implements a Total Hibernate ModeTM which
manages battery life and system efficiency by reducing quiescent current
to just 19µA.
The Application-Specific Power DriversTM (ASPD)
integrate 180V/2A gate drivers for high power applications with 2-level
dead-time protection for the external MOSFET-based inverter. The
Configurable Analog Front-EndTM (CAFE) contains 3
Differential Programmable Gain Amplifiers (PGAs), 4 single-ended PGAs,
10 comparators, buffers and DACs that can be used for signal sampling
and filtering for the control applications, minimizing the need for
“The PAC5532 is our 2nd product release for our new family of
highly integrated BLDC motor control solutions with increased FLASH
memory and an Arm®Cortex®-M4F. It specifically
targets the rapidly growing battery powered power and garden tool
market, but finds use also in new e-mobility,” says David Briggs,
Vice-President and General Manager at Active-Semi. “It is encouraging to
see all the different applications we can service with compacter and
more energy efficient solutions to give our customers a leading edge and
faster time to market.”
In a small 8mm x 8mm QFN package with all of the integration, the
PAC5532 can realize an extremely small BOM and physical design size for
compact high-power BLDC battery-powered applications.
The PAC5532EVK extends the PAC® family of evaluation
kits (EVKs) enabling fast prototyping for various applications including
garden tools, telecom fans, battery-powered vehicles, and
general-purpose BLDC applications. Along with Active-Semi’s motor
control firmware and IP library, the PAC5532 will simplify system
development with sensored and sensorless FOC and sensorless trapezoidal
motor control applications for high-voltage battery powered applications.
PAC5532 IC and PAC5532EVK1 are available from leading distributors.
