Highest performance and smallest footprint advanced PMU solutions for the latest Atmel SAMA5 D2x, and D3x, D4x family eMPUs.

See below for collaterals and links to Xplained board reference designs featuring ACT8865 and ACT8945A PMU solutions.

ActivePMU™ Power management units (PMUs) from Active-Semi enable a wide range of MCUs, MPUs and eMPUs for a broad range of end-applications in industrial, consumer and computing markets. Examples of the end-systems include Point-of-Sale (POS) systems, human-machine interfaces (HMI), control panels, smart grid infrastructures, network gateways, M2M systems, 2D barcode scanners, barcode printers, machine vision equipment, home and commercial building automations, POS terminals and a wide variety of HMI & displays in medical devices and white goods.

ActivePMU™ implements custom coding matrix architecture that allows fast design of PMU solutions for new MCUs, thereby reducing the time-to-market for the customers. ActivePMU™ products feature PMU ICs, evaluation kits (EVKs), reference designs and additional collaterals to cut down on the development time, while offering the best performance and the smallest design footprint.

Active-Semi offers ACT8945A and ACT8865 PMUs for Atmel’s latest SAMA5 D2x eMPUs and also for SAMA5 D3x and D4x family eMPUs. These easy-to-use power management solutions offer highly competitive desigs to reduce the system BOM, reduce power management footprint and offer the best performance in these systems. Both PMUs, and their different code matrix version offer rich design features for system scalability. An example, ACT8945A features ActivePath™ charger, 3 high-performance DC/DC buck converters and 4 LDOs, offering a scalable power management for also supporting DDR memories, peripherals, and system power in POS, HMI and IoT applications. ACT8865 offers the same benefits as above without the ActivePath™ charger.
