摘要： A circuit is used for controlling charging and discharging a battery (320). The circuit comprises a first MOSFET (302) for controlling discharging the battery, and a second MOSFET (304) coupled in series to the battery and the first MOSFET (302) for controlling charging the battery. The first and second MOSFETs have body diodes (312,314) respectively, and the first body diode of the first MOSFET and the second body diode of the second MOSFET are coupled in opposite directions. A load (330) is coupled to the battery and a common node between the first and second MOSFETs such that power in the battery is delivered to said load when the first MOSFET is turned on. The circuit further comprises a power source (310) coupled to the second switch in series and power is delivered from the power source to the battery when the first and second MOSFETs are turned on.

摘要： A signal monitoring system for monitoring a plurality of signals includes a node, a first terminal, a second terminal, and a signal filter. The node receives an input signal and a reference signal selectively. The input signal is selected from the plurality of signals. The first terminal provides an output signal determined by the input signal and the reference signal. The second terminal receives a feedback signal indicative of the output signal. The signal filter comprises energy storage circuitry coupled to the node and the first and second terminals. The energy storage circuitry generates the output signal at the first terminal according to the input signal and the reference signal. The energy storage circuitry also receives the input signal via the node and the feedback signal via the second terminal in alternating fashion. A dominant pole of the signal filter is controlled by the frequency at which the input signal and the feedback signal alternate. The frequency has a first value when the input signal is switched from a first signal of the plurality of signals to a second signal of the plurality of signals. The frequency has a second value less than the first value when a time interval expires.
