摘要： A voltage detection circuit can include a status sensing network and a comparing network. The status sensing network can simultaneously detect a cell voltage for each battery cell of a plurality of battery cells. The comparing network can simultaneously compare the detected cell voltages with a predetermined voltage threshold by comparing the maximum of the cell voltages with a first (high-voltage) threshold, and by comparing the minimum of the cell voltages with a second (low-voltage) threshold. The comparing network can also generate an indication signal when a cell voltage does not satisfy the respective voltage threshold.

摘要： An analog to digital converter (ADC) converts an analog signal to a digital signal. The ADC includes an input channel, a sampling circuit coupled to the input channel, an integrator coupled to the sampling circuit, and a feedback circuit coupled to the integrator. The input channel receives the analog signal. The sampling circuit samples the analog signal. The integrator receives the sampled analog signal and a feedback signal and integrates a superposition of the sampled analog signal and the feedback signal. The feedback circuit generates the digital signal according to an output of the integrator and sends the feedback signal indicative of the digital signal to the integrator.

摘要： A circuit for charging a battery pack includes a transformer and a charger controller. The transformer is operable for receiving an input power and for providing a charging power according to a driving signal to charge the battery pack. The charger controller is operable for monitoring a status of the battery pack, for selecting a charging mode from multiple charging modes according to the status, and for generating the driving signal according to the charging mode to adjust the charging power. The charger controller further executes a state machine that stores data indicating predetermined battery statuses that cause saturation of the transformer, and that selects a protection mode in which said charging power is restricted if the status of the battery pack matches to one of the predetermined battery statuses.
