PAC5285 40V/20W BLDC Motor Controller and Driver with Integrated FETs Product Overview The Qorvo PAC5285 is a 40V/20W BLDC Integrated Motor Controller and Driver with integrated FETs. To enable compact low-power BLDC motor applications, this device integrates a FLASH-programmable MCU, Power Management, Signal Conditioning and 3-Phase BLDC Inverter into a single product. The PAC5285 contains an Arm Cortex -M0 with 32kB of FLASH and 8KB of SRAM and has access to several different analog and digital peripherals used for BLDC motor control and driving. This device has a single 40V power supply input, which makes it ideal for 12V battery-powered applications. There is a charge pump DC/DC that converts the power supply input into an IC and inverter power supply. There are regulators for a 5V system supply, core and analog supplies as well. The device also integrates a differential amplifier that may be used for sensing motor current for over-current protection and motor control. The inverter may be shut down during over-current, over-voltage, under-voltage and over-temperature events. There is also a power monitor that allows the ADC to sample all power supply rails internally. This device contains 6 40V/300m MOSFETs to support 3-phase BLDC motor applications. The PAC5285 is packaged in a 6x6mm, 40-lead QFN package for compact low-power BLDC motors. 1 of 58 PAC5285 Data Sheet REV 0.14 Subject to change without notice PAC5285 40V/20W BLDC Motor Controller and Driver with Integrated FETs Functional Block Diagram Figure 1 Architectural Block Diagram PAC5285 Power Application Controller SWDIO, SWDCL DEBUG 32kB FLASH ARM POWER CORTEX-M0 MANAGER 256B FLASH CORE 8kB SRAM VM VCP HVCP CPL CPH PWM ENGINE CLOCK VSYS CONTROL TIMERS (4) VCORE LDOs VCC33 PWMAx, PWMBx, VCCIO PWMCx, PWMDx PWM/CC (14) RTC MOSFET ASPD INVERTER DEAD TIME VM (7) PCx, PDx, PEx GPIO OUTx BRIDGE VSRC UARTRX, UART UARTTX CAFE WDT SPICSx, SPIMOSI, SPI SPIMISO, SPICLK ISNSP DIFF-PGA PCMP ISNSN DATA ACQUISITION AND SEQUENCER I2CSDA, I2CSCL I2C 10-bit PBTN PB ADC AUTO SYSTEM SAMPLING CONTROL 2 of 58 PAC5285 Data Sheet REV 0.14 Subject to change without notice APB/AHB MUX SOC BUS
