Power Application Controller
1 GENERAL DESCRIPTION
The PAC5232 is a Power Application Controller (PAC) product that is optimized for high-speed motor
control and driving. The PAC5232 integrates a 50MHz ARM Cortex®-M0 32-bit microcontroller core with a
highly-configurable Power manager, Active-Semi’s proprietary and patent-pending Configurable Analog
Front-EndTM and Application Specific Power DriversTM to form the most compact microcontroller-based
power and motor control solution available.
The PAC5232 microcontroller features 32kB of embedded FLASH and 8kB of SRAM memory, a 1MSPS
analog-to-digital converter (ADC) with programmable auto-sequencer, 3.3V/5V IO, flexible clock control
system, PWM and general-purpose timers and several serial communications interfaces.
The Configurable Power Manager (CPM) provides “all-in-one” efficient power management solution for
multiple types of power sources. It features a configurable high-voltage switching supply controller
capable of operating a buck converter, a configurable medium-voltage switching regulator, and four linear
regulated voltage supplies. The Application Specific Power Drivers (ASPD) are 180V power drivers
designed for half bridge, H-bridge, 3-phase, and general purpose driving. The Configurable Analog Front
End (CAFE) comprises differential programmable gain amplifiers, single-ended programmable gain
amplifiers, comparators, digital-to-analog converters, and I/Os for programmable and inter-connectible
signal sampling, feedback amplification, and sensor monitoring of multiple analog input signals.
