Product details
Overview
PAC55710QMSR from Qorvo is a Power Application Controller® (PAC) IC optimized for high-speed BLDC motor control, integrating a 150MHz Arm® Cortex®-M4F core, 128kB FLASH/32kB SRAM, 2.5MSPS 12-bit ADC, and proprietary Multi-Mode Power Manager, Configurable Analog Front-End, and Application Specific Power Drivers in a single 48-pin TQFN package.
For engineers reviewing the PAC55710QMSR datasheet, pinout, applications, or equivalent options, this device supports real-time current regulation via Cycle-by-Cycle PWM truncation, VDS sensing, BEMF comparator mode with virtual center-tap, and CAN 2.0A/B communication for closed-loop motor systems.
Technical Context
The PAC55710QMSR implements a tightly integrated system-on-chip architecture where the Arm Cortex-M4F core executes motor control algorithms while the MMPM manages power conversion (buck or SEPIC), linear regulators, and fault monitoring. Its CAFE provides 10 analog I/O pins, 3 differential and 4 single-ended programmable gain amplifiers, 10 comparators, and dual DACs (10-bit + 8-bit) for sensor signal conditioning and protection.
The ASPD subsystem delivers 3 high-side and 3 low-side gate drivers (1.2A/1.8A drive strength) with configurable propagation delay, fault protection, and two distinct Cycle-by-Cycle PWM truncation modes for precise phase current regulation-enabling direct driving of half-bridge, 3-phase, or IPM topologies without external driver ICs.

FAQ
What is the maximum operating voltage for PAC55710QMSR's main power input?
The PAC55710QMSR accepts a direct battery supply from 5V to 20V on its VBAT pin, feeding the Multi-Mode Power Manager for internal buck/SEPIC conversion and linear regulator generation. This range supports common 2S–5S Li-ion battery packs used in power tools and e-mobility applications. Exceeding 20V may damage the MMPM section. The PAC55710QMSR datasheet specifies absolute maximum rating of 22V for VBAT.
Does PAC55710QMSR support sensorless BLDC commutation?
Yes, the PAC55710QMSR supports sensorless BLDC commutation through its integrated Configurable Analog Front-End, which includes a dedicated BEMF comparator with virtual center-tap mode. This feature eliminates the need for external op-amps or resistor dividers to reconstruct neutral point voltage, enabling reliable six-step or FOC-based commutation using only motor phase voltages. The PAC55710QMSR's DTSE engine synchronizes ADC sampling to PWM edges for precise zero-crossing detection.
What communication interfaces does PAC55710QMSR include?
The PAC55710QMSR integrates CAN 2.0A/B, three USARTs (configurable as UART or SPI), and I²C Master/Slave interfaces. Each USART supports SPI up to 25MHz or UART up to 1Mbps. CAN enables robust, noise-immune communication in motor control networks, while SPI and UART support debugging, parameter upload, and host microcontroller interfacing. The PAC55710QMSR does not include USB or Ethernet peripherals.
How many gate drivers does PAC55710QMSR provide, and what are their drive strengths?
The PAC55710QMSR provides six integrated gate drivers: three high-side (HS0–HS2) and three low-side (LS0–LS2). High-side drivers deliver up to 1.8A peak sink/source current, while low-side drivers deliver up to 1.2A. These drivers support direct connection to N-channel MOSFETs in half-bridge or 3-phase configurations and include configurable propagation delay, fault blanking, and Cycle-by-Cycle PWM truncation for current regulation. The PAC55710QMSR does not support P-channel high-side drivers.
Is PAC55710QMSR pin-compatible with other PAC55xx family members?
No, PAC55710QMSR is not pin-compatible with PAC55711QMSR or earlier PAC55xx variants. While both PAC55710QMSR and PAC55711QMSR use the same 48-pin TQFN package, Figure 8-3 of the datasheet shows functional pin differences-including nDRVDIS and nBRAKE signals present only on PAC55711QMSR. Designers must verify pin mapping against the specific variant's datasheet; migration between PAC55710QMSR and PAC55711QMSR requires PCB layout changes.
