PAC5556QX

Overview

The PAC5556QX is a high-voltage brushless DC (BLDC) motor controller and driver manufactured by Qorvo. It integrates an ARM Cortex-M0 microcontroller with 32kB of FLASH memory, power management circuitry, gate drivers, and signal conditioning into a single system-on-chip (SoC). The device supports three half-bridge outputs for driving up to three-phase inverters, operating at a maximum load voltage of 600V and delivering an output current of 1A per channel. It features a 1.33MHz operating frequency and includes interfaces such as I2C, SPI, UART, and GPIO for system connectivity.
