Qorvo's PAC5232 belongs to Qorvo's Power Application Controller® (PAC) product family. This family features highly-optimized SOC devices that can implement BLDC or PMSM programmable motor controller and driver in a single integrated IC.
The product integrates a FLASH-based MCU, power management, high-side and low-side gate drivers and signal-conditioning components in a single product.
PAC5232 is optimized for 48 V to 120 V battery-powered BLDC applications such as garden tools or battery-powered bikes and scooters.
PAC5232 contains a 50 MHz Arm® Cortex®-M0 with 32 kB of FLASH that can be used to implement high-performance motor control and supervisory applications. The MCU also contains motor control peripherals such as 10b 1MSPS dual auto-sequencer ADC, PWM timers with hardware dead-time insertion, etc. The Multi-Mode Power Manager™ (MMPM) contains a 160 V Buck DC/DC controller and power management components for powering the IC and other PCB system power supplies. The Application-Specific Power Drivers™ provide integrated gate drivers for use with an external inverter. The Configurable Analog Front-End™ (CAFE) provides signal-chain components such as differential and single-end amplifiers, comparators and DACs.
Typical Applications
- Garden Tools (up to 120 V)
- Battery Powered Vehicles
- 48 V Telecom / DC Fans
