ACT8847 Advanced PMU for Multi-core Application Processors INTEGRATED POWER SUPPLIES • Four DC/DC Step-Down Buck Regulators 2 x 2.8A, 2 x 1.5A • Five Low-Noise LDOs 2 x 150mA, 3 x 350mA • Three Low-Input Voltage LDOs 1 x 150mA, 2 x 350mA • One Low IQ Keep-Alive LDO • Backup Battery Charger SYSTEM CONTROL AND INTERFACE • Six General Purpose I/O with PWM Drivers • I2C Serial Interface • Interrupt Controller SYSTEM MANAGEMENT • Reset Interface and Sequencing Controller Power on Reset Soft / Hard Reset Watchdog Supervision Multiple Sleep Modes • Thermal Management Subsystem • Tablet PC • Mobile Internet Devices MID • Ebooks • Personal Navigation Devices The ACT8847 is a complete, cost effective, and highly-efficient ActivePMUTM power management solution optimized for the power, voltage sequencing and control requirements of Samsung Exynos 4210 S5PC210/S5PV310 and other application processors. Please See Ordering Information Section and its Appendix. The ACT8847 features four fixed-frequency, current-mode, synchronous PWM step-down converters that achieve peak efficiencies of up to These regulators operate with a fixed frequency of 2.25MHz, minimizing noise in sensitive applications and allowing the use of small external components. These buck regulators supply up to 2.8A of output current and can fully satisfy the power and control requirements of the multi-core application processor. Dynamic Voltage Scaling DVS is supported either by dedicated control pins, or through I2C interface to optimize the energy-pertask performance for the processor. This device also include eight low-noise LDOs up to 350mA per LDO , one always-ON LDO and an integrated backup battery charger to provide a complete power system for the processor. The power sequence and reset controller provides power-on reset, SW-initiated reset, and power cycle reset for the processor. It also features the watchdog supervisory function. Multiple sleep modes with autonomous sleep and wake-up sequence control are supported. The thermal management and protection subsystem allows the host processor to manage the power dissipation of the PMU and the overall system dynamically. The PMU provides a thermal warning to the host processor when the temperature reaches a certain threshold such that the system can turn off some of the non-essential functions, reduce the clock frequency and etc to manage the system temperature. The ACT8847 is available in a compact, Pb-Free and RoHS-compliant TQFN66-48 package. Innovative PowerTM ActivePMUTM is a trademark of Active-Semi. I2CTM is a trademark of NXP.
