    摘要: A power supply system includes a rechargeable battery to deliver a supply current to a load and a circuit to limit a discharge current when the rechargeable battery is supplying power to the load. The power supply system may further include an integrator for integrating a discharge voltage representing the discharge current that exceeds a predetermined limit, a pulse-width-modulation (PWM) circuit for producing a control signal having a PWM duty cycle representing the discharge voltage, and a driver circuit for delivering the supply current to said load according to said control signal. In one embodiment, a digital register is used to set the battery discharging current limit, in another embodiment an analog circuit is used to set the battery discharging current limit, and in yet another embodiment or a combination of the digital register and analog circuit is used to set the battery discharging current limit.

    摘要: The disclosed embodiments provide an apparatus that controls a current drawn from an adapter by a computer system. During operation, the apparatus senses the current drawn from the adapter using a first current sensor and a second current sensor, wherein a response time of the first current sensor is faster than a response time of the second current sensor. Then, when the current sensed using the first current sensor exceeds a predetermined high-current threshold, the apparatus limits the current drawn from the adapter to a first predetermined current limit. Additionally, when the current sensed using the second current sensor exceeds a predetermined thermal-limit current, the apparatus limits the current drawn from the adapter to the predetermined thermal-limit current.

    摘要: A power supply system and method for operating same. The power supply system is connectable to receive power from an adapter and supply power to a load. The power supply system includes a rechargeable battery, a buck mode circuit, and a boost mode circuit. A switching circuit switches between the buck mode circuit and boost mode circuit for supplying power to the load. If the power required by the load reaches a first predetermined level related to an adapter overload condition for a first predetermined time, the switching circuit disconnects said buck mode circuit from the load and connects the rechargeable battery and the boost mode circuit to said load. The first predetermined level may be established by a first predetermined percent of the current of a dynamic power management level established by the load, which is related to a power level below that which can be provided by the adapter.
