Diodes ZXCT11xx series low-power, high-side current monitors

With an operating current of 3 µA, the ZXCT11xx series of low-power, high-side current monitors from Diodes 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 to 36 and their extended -40 to 125°C temperature range are suitable for higher supply voltage motor vehicle, industrial and whitegoods circuit design.

Requiring a single external gain setting resistor in addition to a low value sense resistor, the monitors 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.

Offering a range of pin-outs to help optimise board layouts, they are 3-pin SOT23 package variants.
