  • Apparatus and method for switching charging supply of a power amplifier
    Patent number: 7425817
    Abstract: A method and apparatus of controlling battery charging of an RF power amplifier are disclosed. The RF power amplifier is supplied by the battery when charging is progressing normally, but switches supply to the charger if the charging process is interrupted. A thermal detector detects a threshold temperature in the battery. A power controller provides feedback to a charger. The charger output is regulated in response to the battery feedback and the charging is suspended when the battery temperature exceeds the threshold temperature. After the charging is suspended, the charger output is regulated to maintain a minimum output voltage. Using a signal from logic circuitry, if charging has been suspended a first switching means disconnects the negative terminal of battery from ground and a second switching means connects the RF power amplifier to the charger.
