Low power current monitors from Diodes Incorporated provide accurate current measurement

Coupled with their low operating current performance, the devices' wide common-mode voltage range, of 2.5V to 36V, and their extended -40ºC to 125ºC temperature range, are well suited to higher supply voltage automotive, industrial and white goods circuit design.

Requiring just 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.

Offering a range of pin-outs to help optimize board layouts, the ZXCT1107 and ZXCT1109 are 3-pin SOT23 package variants. The ZXCT1110 is a 5-pin device with a separate ground pin facilitating improved performance. The parts are priced from $0.3 each in 10k quantities.
