When a chip is in standby mode, its power consumption is defined by its low quiescent current (IQ), which refers to a circuit’s quiet state when it isn’t driving any load. Low IQ extends the length of standby operations in battery-powered automotive and industrial components such as battery management system (BMS) monitors, BMS chargers, voltage supervisors and DC/DC converters. But these devices do need to consume a certain amount of IQ in standby mode in order to sustain high-priority functions and essential functional safety features, along with fast system wakeup to active mode.
