DALLAS, March 20, 2013

DALLAS, March 20, 2013 /PRNewswire/ -- Texas Instruments Incorporated (TI)
(NASDAQ: TXN) today introduced a complete reference design that provides
designers all the analog and embedded processing integrated circuits (ICs)
required for automotive emergency call (eCall) systems. Vehicles equipped with
eCall systems will automatically place calls to an emergency service center in
the event of an accident. Customers can accelerate the design of their eCall
systems by taking advantage of this reference solution comprised of AEC-Q100
qualified analog ICs from TI.

Featuring the TPA3111D1-Q1 high efficiency mono Class D audio amplifier and
the TPS43330-Q1, single-boost, dual synchronous buck controller with ultra low
quiescent current, TI's automotive eCall reference design offers a robust,
low-cost solution that is scalable for other automotive applications, such as
telematics, stolen vehicle tracking and HEV/EV sound generation. It also
incorporates the TLV70033-Q1 voltage regulator with low quiescent current and
the MSP430F2232 16-bit ultra-low power microcontroller. For more information,
to order samples or to download the reference design, visit
www.ti.com/autoecallrefdesign-pr.

Key features and benefits of TI's automotive eCall reference design:

  oLoud and clear audio quality: The TPA3111D1-Q1 delivers 10-W output power
    at 8Ohm with greater than 90 percent efficiency, and offers enhanced EMI
    suppression to improve sound immunity. This ensures loud and clear audio
    quality; which is imperative in an eCall system where external conditions
    can sometimes overwhelm the emergency call.
  oEmergency operation: The TPS43330-Q1 pre-boost circuit supports automotive
    start/stop and boosts back-up battery supply voltage, allowing operation
    down to 2 V at the input. Combined with the Class D amplifier's wide
    supply voltage range of 8 V to 26 V, the components in this reference
    design can be powered by a single-cell LiFePO4 battery, in case the car
    battery connection is severed in an accident.
  oSystem protection: The components offered in this system provide
    over-voltage and load dump protection against input transients of up to 40
    V. The Class D amplifier also supports power cycling and speaker open-load
    detection during initial power-up. These features ensure robust operation
    in harsh automotive environments and simplify failure analysis.
