ACT8847

REV 9, 27-June-17

Advanced PMU for Multi-core Application Processors

FEATURES

GENERAL DESCRIPTION

INTEGRATED POWER SUPPLIES

The ACT8847 is a complete, cost effective, and

highly-efficient ActivePMU^TMpower 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.)

 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

The ACT8847 features four fixed-frequency,

current-mode, synchronous PWM step-down

converters that achieve peak efficiencies of up to

97%. 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-per-

task 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.

 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

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.

 Watchdog Supervision

 Multiple Sleep Modes

 Thermal Management Subsystem

APPLICATIONS

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.

 Tablet PC

 Mobile Internet Devices (MID)

 Ebooks

 Personal Navigation Devices

The ACT8847 is available in a compact, Pb-Free

and RoHS-compliant TQFN66-48 package.
