goods. This device integrates the ActivePath^TM

complete battery charging and management system

with seven power supply channels.

 I²C^TMSerial Interface

 Advanced Enable/Disable Sequencing Controller

 Minimal External Components

 Tiny 5×5mm TQFN55-40 Package

0.75mm Package Height

This device features three step-down DC/DC

converters and four low-noise, low-dropout linear

regulators, along with a complete battery charging

solution featuring the advanced ActivePath^TM

system-power selection function.

Pb-Free and RoHS Compliant

The three DC/DC converters utilize

a high-

efficiency, fixed-frequency (2MHz), current-mode

PWM control architecture that requires a minimum

number of external components. Two DC/DCs are

capable of supplying up to 1100mA of output

current, while the third supports up to 1200mA. All

four low-dropout linear regulators are high-

performance, low-noise regulators that supply up to

320mA of output current.

GENERAL DESCRIPTION

The ACT8945A is a complete, cost effective, highly-

efficient ActivePMU^TMpower management solution,

optimized for the unique power, voltage-

sequencing, and control requirements of the Atmel

SAMA5D2 ,SAMA5D3 series: SAMA5D[31/33/34/35/36],

and Atmel SAM9 series: SAM9G[15/25/35/45/46],

SAM9X[25/35], SAM9M[10/11], SAM9N[11/12]

processors. It is ideal for a wide range of high

performance portable handheld applications such as

The ACT8945A is available in a compact, Pb-Free

and RoHS-compliant TQFN55-40 package.
