    摘要: A Bluetooth audio chip with multiple input/output sources is implemented on a monolithic integrated circuit. The Bluetooth audio chip includes a Bluetooth Baseband/RF module, an encode/decode module, a stereo ADC/DAC codec module, a USB module, a UART module, and a flash memory. Each one of the modules receives/transmits one kind of audio source, thus the Bluetooth audio chip has deeply embedded with multiple input/output sources. The Bluetooth audio chip is used in a diversity of applications to reduce the cost and time comparing to one purpose chip for just only one specific application.

    摘要: A charging control system for lithium battery is provided, and it detects the existing voltage of the charging lithium battery by a voltage detector and passes this voltage value to a microprocessor preset in the hand-held apparatus. Thus, the microprocessor can decide the applicable charge stage and confirm the status of the charging battery depending on the different voltage values in real time. Next, the microprocessor controls a control unit by a pulse width modulation signal to modulate the power-source, which comes from an adaptor, as a constant current or a constant voltage to charge the battery. Accordingly, the charge process is completed by repeating the voltage detection and the duty cycle modulation of the control unit.
