The TWL4030 is the optimized all-in-one audio and power manager to a host of OMAP processors. It is an integrated power management/audio codec device intended for use in portable cellular telephone designs which derive their power from batteries based on Lithium-Ion, Lithium-Ion Polymer or Cobalt-Nickel-Manganese chemistries. The OMAP Platform and TWL4030 combination boost system performance , maximize battery life and reduce board space.
It combines TI's SmartReflex™ power and performance management technology compliant LDOs and DC/DC converters, an audio/voice codec , class- AB/D audio amplifiers, high speed USB 2.0 transceiver, battery charger circuitry and much more into a highly integrated single chip. In addition to audio/voice codecs and amplifiers, the audio resources on the TWL4030 include stereo/mono audio support for speakers, earpiece and headsets, analog and digital mixing, analog/digital microphone support as well as noise cancellation circuitry. The advanced battery charger system features support for charge via AC adapter, USB or carkit standard in addition to back-up battery management, battery presence and over voltage detection. Self contained voltage regulators and converters along with the integrated keyboard interface, LED and vibrator drivers, and real-time clock reduces the need for additional external components.
