AnalogicTech Extends BatteryManager(TM) Product Family With Tiny USB/AC Adapter Battery Charger IC

May 08, 2006

Compact Device Delivers Up to 300mA in 2.0x2.1mm SC70JW Package

    SUNNYVALE, Calif., May 8 /Xinhua-PRNewswire/ --
Advanced Analogic Technologies Incorporated (AnalogicTech)
(Nasdaq: AATI), a developer of power management
semiconductors for mobile consumer electronic devices,
today announced the AAT3681, an extremely small,
single-cell Lithium-ion/polymer battery charger IC designed
to operate from either a USB or an AC adapter on the same
input. This latest addition to AnalogicTech's rapidly
growing battery charger IC product line supports the latest
generation of space-constrained ultra-portable applications
by supplying up to 300mA in a tiny SC70JW package.

    "Many emerging portable applications -- such as
Bluetooth(TM) headsets, high-end portable music players,
and compact digital cameras -- use extremely small
batteries that require tiny low-power battery
chargers," said Bill Weiss, Product Line Director for
AnalogicTech. "By offering a simple, complete USB/AC
adapter battery charger in an ultra-small 2.0x2.1mm SC70JW
package, the AAT3681 allows designers to meet tight space
constraints, reduce development time, and quickly get their
product to market."

    Complete Solution

    The AAT3681 integrates a charging device and reverse
blocking diode to precisely regulate battery charge voltage
and current for 4.2V Lithium-ion/polymer battery cells. It
operates from a DC power source or USB port across a 4.0V
to 6.5V input voltage range. 

    The device's adapter/USB charge input constant current
level can be programmed up to 300mA for rapid charging. The
AAT3681 includes a status monitor output pin capable of
directly driving an external LED to indicate battery charge
state. Other than optional decoupling capacitors, the device
requires only a single external resistor for complete
functionality.  

    Protection circuits in the AAT3681 continuously monitor
the charge state for fault conditions. If an over-voltage,
short-circuit, or over-temperature condition occurs, these
circuits automatically shut down the AAT3681 to protect the
charging device, control system, and battery under charge.
 
    First ModularBCD(TM) Production Device

    The AAT3681 is AnalogicTech's first production device
developed in its proprietary new ModularBCD process
technology. This new process differs from conventional BCD
technologies by using a low-temperature, CMOS-like flow
capable of achieving high yields while ensuring device
performance and electrical isolation. By allowing
AnalogicTech's designers to easily add or remove modules
and devices with different supply voltages, this new highly
modular process vastly simplifies analog and mixed-signal
circuit reuse. The AAT3681 battery charger IC is a
standalone product and is a key ModularBCD building block
for upward integration into power systems-on-chip.

    Price and Availability

    Specified over the -40 degrees C to +85 degrees C
temperature range, the AAT3681 is available in a Pb-free,
8-pin 2.0x2.1mm SC70JW package. The device sells for $0.76
in 1000-piece quantities.
