Zetex Offers New ZXCT 1010 Current-Sense IC

Zetex Semiconductors (UK) announced the new ZXCT 1010, which provides a simple and cost-effective means of accurately measuring load current with a sense resistor. The current-sense monitor IC uses a single scaling resistor to convert the current into a ground-referenced output voltage and eliminates ground plane disruption.

An enhanced version of the companion ZXCT1009 device, the ZXCT1010 high-side current-monitor IC features a separate pin-to-ground that improves the typical output offset from 500mV to 30µV.

Offering an improved sensing accuracy of one percent, the SOT23-5 packaged current monitor is suitable for portable battery-powered equipment, low-cost battery chargers, automotive applications, dc motor controllers and other equipment requiring a simple, cost-effective current-measuring solution. With a low quiescent current of just 4µA, the ZXCT1010 operates over a broad input-voltage range, from 20V down to as low as 2.5V.

The 1,000-piece price is $0.54 each. Samples and start-up quantities are now available and delivery is six weeks.
