Qorvo claims smallest motor controller

Qorvo has introduced what it claims to be the industry’s smallest single-chip motor control and inverter product for brushless DC (BLDC) motors.

The integrated, single-chip design enables motor control for compact, low-power 2S to 8S battery-powered BLDC motors and opens the door to new markets and electronics in health and beauty, among others.

The Qorvo PAC5285 Power Application Controller (PAC) integrates within a single product a high-performance, 50 MHz Arm Cortex-M0 with 32kB of FLASH, power management, gate drivers, integrated MOSFET inverter and signal conditioning components.

This provides significant savings on both the PCB size and bill of materials (BOM) count while enabling high-performance motor control with extended battery life.

The PAC5285 BOM has reduced the number of external passive components – no other ICs or active components are required for this high-performance, programmable BLDC solutions.

The PAC5285 is available now and offers these features:

PAC5285
  • Integrated FLASH-programmable MCU
    • 50 MHz Arm® Cortex®-M0 with 32 kB FLASH
    • 10-bit 1 MSPS SAR ADC with dual sequencer
    • PWM Timers, Serial Communication
  • Integrated Power Management
    • 40 V Input Charge Pump DC/DC, LDOs
    • 8 µA@12V low-power hibernate mode
  • Integrated Gate Drivers and MOSFETs
    • 6 x 40 V / 300 mΩ MOSFETs for BLDC 3-phase motors
  • Integrated Signal Conditioning
    • Integrated Differential and Single-ended Amplifiers
