Qorvo – Power Application Controller Update

Power Application Controller UpdateThe family of Power Application Controller (PAC) is currently being expanded by Qorvo! In addition to the specialised SoCs for motor control applications that have been available for several years, the first products for battery management are now available.

This new sub-family adopts the successful concept of combining a Cortex M0 or Cortex M4F microprocessor with specialised analogue and power peripherals for each specific application.


Power Application Controller Architecture

In the PAC, a digital MCU part is combined with an application-specific analogue part. The following block diagrams provide an overview

Batterie-Management

Power Application Controller Update

Due to this flexibility, Qorvo is able to support the most diverse applications in the respective applications. The choice between a Cortex M0 or a Cortex M4F based PAC enables both standard applications and systems with advanced requirements to be realized. These two platforms offer

Cortex M0

  • 50 MHz Main Clock
  • up to 32 kB Flash
  • up to 8 kB SRAM
  • 10 Bit 1 Msps ADC
  • Serial IF – UART, SPI, I2C

Cortex M4F

  • 150 MHz Main Clock
  • up to 128 kB Flash
  • up to 32 kB SRAM
  • 12 Bit 2.5 Msps ADC
  • Serial IF – UART, SPI, I2C, CAN

NEW: PAC for Battery Management

The new sub-family starts with 2 derivatives PAC2X214 (X: 2 – M0 / 5 – M4F) for 10 to 20 cells, i.e. for systems in the 40/48V up to 80/90V range, and thus addresses in a first step applications in

  • e-Bikes & e-Scooter
  • autonomous & steered gardening tools
  • big power tools: chain saws, leaf blowers, core drills

For this purpose, intelligent battery packs can be realised through the high integration of all necessary components. The analogue section is divided into three main function blocks

  • Configurable Power Manager
    •  145 V DC/DC Buck Regler
    • FET driver for high-side
    • LDO for additional functional groups like sensors or wireless modules attached to the PAC
  • Driver dedicated to Battery Management
    • FET driver for charging and discharging FETs
    • FET driver for external fuse
    • Balancing FETs (50 mA)
  • Configurable Analog Front End (CAFE)
    • For current measurement: 16 Bit Sigma-Delta ADC with differential inputs and programmable gain amp (PGA)
    • For voltage monitoring & cell balancing: 16 Bit Sigma-Delta ADC
    • 10 Bit SAR ADC for voltage- / temperature sensing
    • DACs, comparators
    • Monitoring & protection functions (Over Charge, Over Discharge & Short-Circuit, Protection)

PAC Product Guide


Development tools and application support are already to hand (z.B. für PAC25214). We will be happy to inform you about further details. Contact us directly or send us your enquiry via the web form at the end of this article.


PAC for Motor Control

We have already published several news about the Power Application Controller PAC5Xxx (X: 2 – M0 / 5 – M4F) for motor control (BLDC & PMSM). See here a brief overview of the currently available portfolio.

Basically, derivatives can be divided into 4 voltage classes:

40 – 52V

70 V

160 V

600 V

PAC5222, PAC5285 (internal MOSFETs), PAC5526/7 (more digital I/O)

PAC5223, PAC5225, PAC5524, PAC5523A

PAC5232, PAC5532

PAC5210 (for IPM Control), PAC5253, PAC5255, PAC5256 (HV Buck), PAC5556A (HV Buck)

Especially remarkable is the PAC5285 with itegrated MOSFETs for motor control and DC/DC with charge pump. More you find here.

The PAC5x56 also offers interesting possibilities with HV Buck support (cost reduction in applications with non-isolated power supply), MV Buck regulator instead of LDO to increase efficiency, PWM timer with dead time generation in hardware as well as a “Cycle-by-Cyle OC” (overcurrent detection & protection).
