Zetex Intros High-Side Current Monitor
High-side current monitor IC.
Hauppauge, NY — The new ZXCT1080 current monitor from Zetex Semiconductors has an extended, common-mode-sensing voltage range of 3V to 60V. This simplifies high-side current sensing in a wide range of high-voltage circuit protection applications, including automotive, industrial motor control and power supplies. The device reduces the number of current-measuring external resistors to only one.

It does this through a gain-setting resistor with a fixed gain of 10V. This reduction in circuit complexity, combined with the monitor's SOT23-5 package, reduces footprint size and production costs.

Working off a separate 4.5V to 12V supply voltage, the device's ground-referred output voltage can be closely matched with A-D converters and microcontrollers, and be protected against harmful over-voltage conditions. Characterized by a low-quiescent current, typically 80µA, the monitor reduces the errors incurred in translating actual measured current into the input sense current required, and into overall power consumption as well.
