Current monitors feature ultrawide operating range

The new high-side current monitors from Supertex Inc. feature an ultrawide operating range (8V to 450V) for motor controls, off-line sensors, instrumentation amplifiers, and current-sensing for high-voltage LED drivers, batteries and switchmode supplies.

"With their wide input voltage range, fast response time and low quiescent current, the HV7801 and HV7802 are well suited for a vast array of current sensing applications," said Ahmed Masood, vice president of marketing for Supertex. "While the HV7801 features a fixed gain of five, the HV7802 also allows users the additional flexibility of programming the voltage or transconductance gain."

The HV7801 is available in a 5-lead SOT23 package (HV7801K1-G), while the HV7802 is offered in an 8-lead MSOP package (HV7802MG-G). The parts are green and RoHS compliant. Samples are available from stock. Lead time for production quantities is 6-8 weeks ARO.

The HV7801K1-G is priced at 56 cents, and the HV7802MG-G at 62 cents, both in 1,000-unit quantities.
