TI’s three new smart battery management
integrated circuits improve measurement and
protection of multi-cell, lithium-based batteries
used in power tools, e-bicycles, and portable
medical and test equipment. The battery
management controller bq78PL114 provides
complete lithium battery system control,
monitoring and safety functions for 4-series cells.
By leveraging the PowerLAN communications
interface, a designer can combine multiple
bq76PL102 dual-cell monitor devices with this
Linear Technology Corporation announces
the LT3080, a 1.1A 3-terminal LDO that may
be easily paralleled for heat spreading and
is adjustable with a single resistor. This new
architecture regulator uses a current reference to
allow sharing between multiple regulators with
a small length of PC trace as ballast, enabling
multi-amp linear regulation in all surface-mount
systems without heat sinks.
The LT3080 achieves high performance
without any compromises. Featuring wide input
Gain a Highly Efficient and Flexible Pointof-Load
Power Conversion Solution with
Fairchild’s Digital Power Controllers
These digital power controllers combine
digital loop control with highly integrated power
management capabilities to offer flexible, easyto-design
power delivery solutions. These
controllers address a wide variety of complex
power system requirements found in applications
Magnetics is pleased to announce the
addition of XFLUX TM , a distributed air gap 6.5%
SiFe material, to our existing powder core line. A
true high temperature material, with no thermal
aging, XFLUX offers lower losses than powder
iron cores and superior DC Bias performance.
XFLUX cores are ideal for low and medium
frequency chokes where inductance at peak
is critical. One of the many challenges facing
designers of high power circuits is maintaining
Microchip Offers Free Field Oriented Control
Algorithm for New Low-Cost Motor Control
Digital Signal Controllers
Microchip announces 10 new 28- and 44-pin
16-bit Digital Signal Controllers (DSCs) for motor
control designs requiring increased memory,
performance, or enhanced peripherals, while
obtaining cost and size savings by using lower
pin-count devices. Additionally, Microchip
controller to create a smart battery solution for
up to 12 rechargeable cells. Another degree of
integration, safety and protection to multi-cell
applications is added with bq77PL900, the new
lithium-based battery protector and analog front
end for 5- to 10-cell battery systems.

voltage capability from 1.2V to 40V, it has a low
dropout voltage of only 300mV at full load. The
output voltage is adjustable, spanning a wide
range from 0V to 40V, and the on-chip trimmed
reference achieves high accuracy of +-1%. The
wide V IN & V OUT capability, tight line and load
regulation, high ripple rejection, low external
parts count and parallel capability make it ideal
for modern multi-rail systems.

inductance in the power choke at maximum
load. XFLUX is the cost-effective solution to
getting enough inductance in a reasonable size
package.
Seven toroid sizes (60 permeability) are
currently available. Outside diameters range
in size from 21mm to 47mm. New sizes and
permeabilities will be added in the future.
