The ZXCT1080 current monitor from Zetex Semiconductors features an extended, common-mode-sensing voltage range of 3 V to 60 V
The ZXCT1080 current monitor from Zetex Semiconductors features an extended, common-mode-sensing voltage range of 3 V to 60 V, simplifying high-side current sensing in high-voltage circuit protection applications.
Device type: High-side current monitor IC with voltage output Supply voltage: 4.5 V to 12 V Sensing voltage range: 3 V to 60 V Quiescent current: 80µA typ. Operating temperature range:-40ºC to 125ºC Packaging: 5-pin SOT-23 Target applications: automotive, industrial motor control, and power supplies Pricing: $0.788 each in quantities of 1000 Availability: available now Data sheet posted on web? yes, see www.zetex.com/3.0/product_portfolio.asp? pno=ZXCT1080&h=15
Notes: IC reduces the number of current-measuring external resistors to only one, via a gain-setting resistor with a fixed gain of 10. Ground-referred output voltage can be closely matched with A-D converters and microcontrollers, and protected against overvoltage conditions. An automotive, AEC-Q100-qualified version is also planned for Q1 2008.
