NC – No internal connection The TPS9104 incorporates a plete power supply and audio power system for a cellular subscriber terminal that uses battery packs with three or four NiMH/NiCd cells or a single lithium-ion cell.
The device includes three low-dropout linear regulators rated for 3.3 V or 3 V at 100 mA each, a charge-pump driver, two power amplifiers for a speaker and a ringer, a low-noise microphone amplifier, and logic that includes a 250-ms reset, on/off control, and processor interface.
Regulators A and B and the charge-pump driver are disabled until regulator L (logic regulator) reaches the rated voltage and RESET is logic high.
