The PAC5524 belongs to Active-Semi’s Power Application Controller (PAC) family. The PAC family of products are highly-optimized SOC devices that can implement BLDC or PMSM programmable motor controller and driver in a single integrated IC. The PAC5524 integrates a high-performance, high-memory FLASH-based 150MHz Arm? Cortex-M4F?, Power Management , High-side and low-side Gate Drivers and Signal-Conditioning components in a single product.

五分快三计划The PAC5524 is optimized for high-performance battery-powered BLDC motor control applications up to 48V.


Advantages of our Intelligent Motor Control

High-Performance, high-memory programmable 32-bit MCU Allows implementation of high-performance advanced control algorithms such as Field Oriented Control (FOC), Sensorless BEMF, Sensored BLDC and serial communications protocols
Integrated Power Management Removes the need for an external DC/DC Controller. Provides 5V/200mA system supply for additional PCB peripherals. Integrates all power rails for MCU, FLASH, Analog and gate drivers
Integrated Gate Drivers 3 integrated 70V/1.5A high-side and 3 integrated 1.5A low-side gate drivers for 3-phase inverters
Integrated Signal Chain Allows integrated current, voltage and temperature sensing and protection using integrated Differential and Single-ended Programmable-Gain Amplifiers, comparators and DACs. Hardware-based cycle by cycle current limit
Lowest Standby Power 18μA Iq for standby-mode


Active-Semi’s PAC5524EVK1 evaluation kit is a complete hardware solution enabling users to evaluate the PAC5524 device, but also develop motor control applications revolving around the powerful and versatile 150MHz Arm? Cortex? -M4F based MCU. This evaluation kit is a motor controller and driver evaluation PCB, that uses the PAC5524 Power Application Controller?五分快三计划. To aid in evaluation and application development the PAC5524EVK1 offers access to all of the PAC5524 device’s signals by means of a series of female header connectors.
