PAC5285-T

Application Specific Microcontrollers Overview

The Qorvo PAC5285-T is a highly integrated low-power Brushless DC (BLDC) motor controller and driver designed for compact applications. It features an integrated 3-phase gate driver with FETs, supporting up to 40V input voltage and 20W power handling. The device incorporates a Flash-programmable 32-bit ARM Cortex-M0 microcontroller unit (MCU). Key electrical parameters include a maximum supply voltage of 27V, a minimum operating voltage of 5.5V, and an output current capability of 20mA. The quiescent supply current is specified at 150µA. The component operates within a temperature range of -40°C to +105°C and is housed in a QFN-40 surface-mount package.

Application Specific Microcontrollers Feature Summary

• Integrates a 32-bit ARM Cortex-M0 MCU with Flash programming capabilities alongside the motor driver circuitry.

Application Specific Microcontrollers Procurement Notes

Verify the specific tape-and-reel packaging configuration when ordering the PAC5285-T variant. Confirm that the required firmware or development tools align with the integrated ARM Cortex-M0 architecture. Ensure that the thermal performance of the QFN-40 package meets the application's heat dissipation requirements under the maximum operating temperature of +105°C. Cross-reference the exact part number suffix with official Qorvo documentation to confirm availability and specifications.

Application Specific Microcontrollers Selection Notes

Select the PAC5285-T for applications requiring a single-chip solution for BLDC motor control up to 20W. The integrated FETs and MCU reduce bill-of-materials complexity compared to discrete solutions. Consider the 40V input rating and 27V max supply limit when designing power stages. The wide operating temperature range makes it suitable for harsh environments. Evaluate the 150µA standby current for battery-sensitive designs.
