The AT73C201 integrates all the regulated power supplies needed to power a terminal chipset from a Lithium-Ion or Ni-Mh battery pack to Baseband ICs and Memories, Radio Transceiver, Analog, VCXO, LNA and PA bias and Sim Card in the case of GSM. Auxiliary low Ron power supply PMOS switches are available from either the battery pack or internal regulated power supplies, providing optimum power management by turning on or off different elements of a handset. The AT73C201 also includes a vibrator motor driver, a set of LED drivers, a smart reset circuit, and a Battery Charger Switch Driver with built-in state machine for safe boot and pre-charge operation. In addition, a set of 3 Audio Programmable Gain Amplifiers are provided for handsfree (on 8 Loudspeaker), Earpiece and Car Kit easy interfacing. The functions are supervised by a set of voltage monitors, timers and a temperature shutdown circuit connected to the internal state machine. Voltages and on-chip temperatures are also visible from an external pin through a multiplexer for proper connection to the external Baseband ADC. The AT73C201 is available in a 9x9mm outline, 10x10 ball matrix BGA for optimum size and performance combination. Its very low standby power dissipation and its high noise and PSRR performances make the AT73C201 ideally suitable for recent applications on 2.5G and 3G terminals. 2741AS-PMGMT-11/03 Note: This is a summary document.
