PRODUCT DATASHEET

AAT3608

SystemPower Compact 7 Channel Regulator with Li+/Polymer Linear Battery Charger and I²C Interface

General Description

Features

•

The AAT3608 is a member of AnalogicTech’s Total Power

Management IC™ (TPMIC™) product family. It contains

a single-cell lithium ion/polymer battery charger, two

800mA switching regulators, and five low dropout (LDO)

regulators in a small Pb-free 40-pin 5mmx5mm TQFN

package, making it ideal for portable space-constrained

systems. The single-input linear charger powers up from

an adapter or a USB port. The adapter charge current is

programmable with an external resistor or pin selectable

between 100mA and 500mA when connected to a USB

port. The device integrates a load switch for dynamic

power path and features deep sleep mode operation. The

step-down regulators are monolithic synchronous con-

verters integrating the compensation network and soft

start circuitry. The 1.5MHz operating frequency enables

the use of tiny 2.2μH inductors and small 4.7μF output

capacitors. External resistors set the output voltage for

Buck 1 and Buck 2; the output voltage of Buck 2 is

dynamically adjustable with I²C. The LDO regulators fea-

ture 3% output voltage accuracy over the full operating

temperature range. The fast control loop of the LDO

regulators also provide excellent transient response with

a typical output voltage deviation of 1.5%. The AAT3608

provides protection features to safeguard from over-

temperature operation, over-current operation, and a

digital thermal loop to protect the battery during battery

charging. The device is rated over an ambient tempera-

ture range of -40°C to 85°C.
