PAC5250
Power Application Controller
1. GENERAL DESCRIPTION
The PAC5250 belongs to Active-Semi's broad portfolio of full-featured Power Application ControllerTM (PAC) products that
are highly optimized for controlling and powering next generation smart energy appliances, devices, and equipment. These
application controllers integrate a 50MHz ARM® CortexTM-M0 32-bit microcontroller core with Active-Semi's proprietary
and patent-pending Multi-Mode Power ManagerTM, Configurable Analog Front EndTM, and Application Specific Power
DriversTM to form the most compact microcontroller-based power and general purpose application systems ranging from
digital power supply to motor control. The PAC52xx microcontroller features up to 32kB of embedded FLASH and 8kB of
SRAM memory, a high-speed 10-bit 1µs analog-to-digital converter (ADC) with dual auto-sampling sequencers,
5V/3.3V I/Os, flexible clock sources, timers, a versatile 14-channel PWM engine, and several serial interfaces.
The Multi-Mode Power Manager (MMPM) provides “all-in-one” efficient power management solution for multiple types
of power sources. It features a configurable multi-mode switching supply controller capable of operating in buck, flyback,
or boost mode, and up to four linear regulated voltage supplies. The Application Specific Power Drivers (ASPD) are high-
voltage and ultra-high-voltage power drivers designed for each target set of control applications, including half bridge, H-
bridge, 3-phase, intelligent power module (IPM), 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. Together, these modules and microcontroller enable a wide range of compact
applications with highly integrated power management, driving, feedback, and control for DC supply up to 52V and for line
AC supply.
