DALLAS, March 25, 2013

DALLAS, March 25, 2013 /PRNewswire/ -- Texas Instruments Incorporated (TI)
(NASDAQ: TXN) today introduced lithium-ion battery charger integrated circuits
(ICs) that reduce charge time by 50 percent in smartphones and tablets
compared to other charger solutions. The bq2419x family of 4.5-A output, 20-V
input-rated switch-mode chargers with I2C interface and USB On-the-Go (OTG)
support delivers faster and cooler charging to a wide array of applications
ranging from power banks and packs to 4G LTE routers, Wi-Fi speakers, portable
medical and industrial designs. For samples visit: www.ti.com/bq24190-pr.

Consumers continue to want faster battery charging in portable electronics.
New designs require more accurate, highly efficient charge circuitry that
keeps the system cool and safe while charging at a faster rate. TI's new
bq24190, bq24192, bq24192i, bq24193, bq24195, bq24195L and bq24196 fast-charge
circuits reduce charge time through battery path impedance compensation, and
offer programmable thermal management capability to ensure the safest, most
reliable system operation.

Key features and benefits of the bq2419x:

  oFaster charging for single-cell lithium battery packs: 4.5-A output, 20-V
    input chargers cut charge time in half with unique battery path impedance
    compensation.
  oCooler charging with highest efficiency: 4.5-A switch-mode charger
    achieves 92-percent efficiency at 2 A and up to 90-percent efficiency at 4
    A of output current. Meets Energy Star and European Union charging
    specifications. Programmable thermal regulation temperature significantly
    improves system-level design.
  oLonger battery run-time: Integrated battery discharge MOSFET provides the
    industry's lowest on-resistance of 12 milliohms.
  oHighest efficiency for USB OTG: 92-percent boost efficiency at 2.1 amps
    with the bq24195.
  oSafe charging: Prevents overvoltage, protects the battery and system
    during charging. bq24193 supports JEITA guidelines.
  oSimple to design: Smallest, most integrated battery charging solution
    (4-mm x 4-mm QFN package) integrates Power Path management, synchronous
    FETs, integrated current sensing, internal loop compensation and bootstrap
    diode.
