With an operating current of 3 µA, the ZXCT11xx Series of low power high-side current monitors from Diodes Incorporated provides accurate, high efficiency measurement of load current in motor drive, overload protection and safety applications. Coupled with their low operating current performance, the devices' wide common-mode voltage range, of 2.5 V to 36 V, and their extended -40ºC to 125ºC temperature range, are suited to higher supply voltage automotive, industrial and white goods circuit design. Requiring a single external gain setting resistor in addition to a low value sense resistor, the ZXCT11xx monitors are simple to use, keep component count to a minimum and save space with their SOT23 packaging. Sensing current on the high-side also avoids any ground plane disruption.
