Low-power Hall-effect devices enable longer operating life in battery-reliant systems through reduction of active current consumption. For example, the DRV5032 low power Hall-effect switch has a 5-Hz sample rate device which consumes a typical current of just 0.54 µA at 1.8-V supply. Current consumption generally has an inverse correlation with device bandwidth, so it is necessary to balance the two characteristics for the intended flow monitoring application. If high bandwidth and low power are required, it may be necessary to lower the average current consumption by externally duty-cycling a sleep or enable pin (if the device has one), or by duty-cycling the VCC pin of the device.
