Product details

Overview

PAC5526QMSR from Qorvo is a 48V Power Application Controller® (PAC) integrating a 150MHz Arm® Cortex®-M4F MCU core, 128kB FLASH/32kB SRAM, 2.5MSPS 12-bit ADC, configurable analog front-end (CAFE), and application-specific power drivers (ASPD) for BLDC motor control. It delivers integrated gate drive (3 high-side/3 low-side), charge pump + buck-boost power management, and CAN 2.0B interface in a single TQFN-48 package.

For engineers reviewing the PAC5526QMSR datasheet, pinout, applications, or equivalent options, this device serves as a system-on-chip solution for battery-powered 48V motor drives-requiring no external gate drivers, voltage regulators, or analog signal conditioning circuitry in typical implementations.

Technical Context

The PAC5526QMSR implements a tightly coupled SoC architecture where the Arm Cortex-M4F core directly controls PWM timing, dead-time insertion (16 hardware generators), and dynamic ADC sampling via the DTSE engine. Its Power Manager provides VM-referenced HVCP (VM + VP) and configurable 10V/12V MVBB outputs to drive high- and low-side MOSFETs independently.

The Configurable Analog Front-End includes 1 differential + 5 single-ended PGAs, 2 DACs, and programmable comparators with cycle-by-cycle over-current protection-enabling real-time current sensing, phase voltage monitoring, and closed-loop feedback without external op-amps or discrete protection circuits.

FAQ

What is the maximum VM input voltage supported by the PAC5526QMSR?

The PAC5526QMSR supports a VM input voltage range of 6V to 48V, with absolute maximum rating of 48V. Operation above 48V may cause permanent damage. The internal HVCP and MVBB regulators are designed to maintain stable gate drive supplies across this full range, enabling compatibility with nominal 48V battery systems including those with transient overvoltage conditions up to 48V.

Does the PAC5526QMSR support Field-Oriented Control (FOC) algorithms?

Yes, the PAC5526QMSR supports real-time FOC implementation via its 150MHz Cortex-M4F core with FPU, 2.5MSPS ADC with DTSE-triggered sampling, and 16 hardware dead-time generators. The integrated CAFE provides differential current sensing capability, and the ASPD enables precise 3-phase gate timing-making it suitable for sensorless or hall-based FOC in 48V BLDC applications without external signal conditioning.

How does hibernate mode function on the PAC5526QMSR?

The PAC5526QMSR achieves ultra-low-power hibernate mode with typical VM supply current of 5µA at 18V. In this state, the MCU core, all LDOs, and power regulators are shut down. Wake-up can be triggered by a configurable timer (8ms–4s) or an external push-button event on AIO6. Upon exit, the device performs full power-up sequence and MCU reinitialization, retaining only persistent power/temperature fault status bits.

Can the PAC5526QMSR operate without external gate driver components?

Yes-the PAC5526QMSR integrates six application-specific power drivers (3 high-side, 3 low-side) capable of 1A peak gate drive current and 100% duty cycle operation. These drivers eliminate the need for external high-side level shifters or discrete gate drivers in standard 3-phase BLDC inverters, reducing component count and layout complexity while maintaining robust shoot-through protection.

What analog sensing capabilities does the PAC5526QMSR provide?

The PAC5526QMSR includes a Configurable Analog Front-End (CAFE) with 1 differential and 5 single-ended programmable gain amplifiers, 2 DACs, 5 comparators (including phase and protection types), and 6 analog I/O pins. This enables direct shunt-based current sensing, phase voltage monitoring, temperature sensing, and over-current protection-all without external op-amps or discrete comparators.
