Product details
Overview
PAC52711QM-T from Qorvo is a Power Application Controller® (PAC) IC integrating a 50MHz Arm Cortex-M0 microcontroller core, Multi-Mode Power Manager, Configurable Analog Front End, and Application Specific Power Drivers for compact motor control and digital power systems. It features 32kB FLASH, 8kB SRAM, 10-bit 1µs ADC with dual auto-sampling sequencers, true 5V/3.3V I/Os, and 3 high-side + 3 low-side gate drivers (1A), targeting e-mobility ESCs and power tools.
For engineers reviewing the PAC52711QM-T datasheet, pinout, applications, or equivalent options, key selection criteria include its 48-pin TQFN package, VDS sensing overcurrent protection, nBRAKE/nDRVDIS safety pins, single-ended CAFE configuration (1 PGA), and 70V DC input capability - all critical for robust, integrated BLDC drive designs.
Technical Context
The PAC52711QM-T implements a tightly coupled system-on-chip architecture where the 50MHz Cortex-M0 core directly controls the 14-channel PWM engine, MMPM switching controller (buck/SEPIC capable), and ASPD gate drivers via hardware-triggered signal paths. Its CAFE includes 10 analog front-end I/O pins, 3 differential PGAs, 1 single-ended PGA (vs. 4 in PAC52710), 10 comparators, and two DACs (10-bit + 8-bit).
Hardware safety features are embedded at the silicon level: nBRAKE and nDRVDIS pins enable immediate gate driver disable and braking during fault conditions; VDS sensing and configurable Cycle-by-Cycle PWM truncation provide real-time current regulation without external shunts; and hibernate mode with power/temperature monitoring supports energy-constrained portable applications.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PAC52710QM-T | Includes 4 single-ended PGAs (vs. 1 in PAC52711QM-T); identical MMPM, ASPD, and PWM resources | Better suited for multi-sensor systems (e.g., dual current + temperature + voltage feedback) | Select PAC52710QM-T when additional analog signal conditioning channels are required; otherwise PAC52711QM-T offers lower cost and smaller footprint. |
| STSPIN32F0B | Integrated 3-phase gate driver + Cortex-M0, but no MMPM, no VDS sensing, and limited analog front end (no PGAs or DACs) | Targeted at basic BLDC drives without advanced power management or sensor-rich feedback loops | Choose STSPIN32F0B only for cost-sensitive, low-feature applications where external DC-DC and analog circuitry are acceptable. |
Compared with PAC52710QM-T and STSPIN32F0B, the PAC52711QM-T delivers optimal balance of integrated power management, hardware safety features (nBRAKE/nDRVDIS), and analog flexibility for mid-tier e-mobility and power tool designs - offering higher functional density than STSPIN32F0B and lower analog overhead than PAC52710QM-T.

FAQ
What is the primary function of the PAC52711QM-T in motor control systems?
The PAC52711QM-T serves as a fully integrated power application controller that combines a 50MHz Arm Cortex-M0 microcontroller, gate drivers, analog front end, and multi-mode power manager into a single chip. In motor control systems, it executes commutation algorithms, manages gate timing, performs real-time current regulation via VDS sensing, and enforces safety actions using dedicated nBRAKE and nDRVDIS pins - eliminating the need for multiple discrete ICs in BLDC and PMSM drives.
How does the PAC52711QM-T differ from the PAC52710QM-T in analog capability?
The PAC52711QM-T integrates only 1 single-ended programmable gain amplifier (PGA) in its Configurable Analog Front End, whereas the PAC52710QM-T includes 4. Both share identical differential PGAs (3), comparators (10), DACs (10-bit + 8-bit), and ADC resources. This reduction makes PAC52711QM-T ideal for applications requiring fewer analog signal paths - such as single-current-loop motor control - while lowering cost and simplifying layout.
Does the PAC52711QM-T support hardware-based braking and driver disable functions?
Yes, the PAC52711QM-T includes two dedicated hardware safety pins: nBRAKE and nDRVDIS. Asserting nBRAKE forces all high-side drivers off and activates the braking path in motor circuits. Asserting nDRVDIS immediately disables all six ASPD gate drivers. Both operate independently of firmware execution, providing deterministic sub-microsecond response for functional safety compliance in power tools and e-mobility systems.
What package type and thermal characteristics does the PAC52711QM-T use?
The PAC52711QM-T uses a 48-pin, 6×6 mm TQFN package with an exposed thermal pad for enhanced heat dissipation. Its thermal resistance (θJA) is 32°C/W under standard JEDEC 2-layer board conditions. The device supports junction temperatures from –40°C to +125°C and includes on-die temperature monitoring within the Multi-Mode Power Manager for thermal fault detection and hibernate mode activation.
Can the PAC52711QM-T operate directly from a 48V battery without external DC-DC conversion?
Yes, the PAC52711QM-T's Multi-Mode Power Manager accepts up to 70V DC input and can configure its internal switching controller in buck mode to generate regulated 5V and 3.3V rails for internal logic and I/O. This allows direct operation from common 36V–48V Li-ion battery packs used in scooters and power tools, eliminating the need for external high-voltage DC-DC converters and reducing system complexity and footprint.
