发明名称 Method for detecting a defective charger circuit
摘要 In a method and system for detecting charger failure, a battery is operable to receive a charge from the charger via a pair of terminals. The battery includes an analog front end (AFE) coupled to the pair of terminals. The AFE is configured to receive at least one input corresponding to voltage measured across the pair of terminals. A battery controller included in the battery is coupled to the AFE by a serial link. The battery controller receives the at least one input via the serial link. In response to the voltage being below a predefined value, the battery controller is placed in a charge_not_received state, which is indicative of the charger being defective.
