Agilent's Single-ended Linear Optocouplers Makes EDN Hot 100 List

1/16/2004 - Agilent Technologies Inc. (NYSE: A) announced that its HCPL-7510 and HCPL-7520 single-ended linear optocouplers have been named an EDN Hot 100 Product of 2003.

EDN magazine's technical editors analyze and compare the industry's product introductions and make their selections at the end of each year. Product descriptions can be found in EDN's Dec. 11, 2003, issue and on

Motor drive and control system designs must accurately sense motor current in noisy environments and maintain galvanic isolation between the low-voltage and high-voltage sides of the circuit. The Agilent optocouplers accomplish these critical tasks by sensing the voltage drop through the external sense resistor, and developing a proportional output voltage on the other side of the optical-isolation barrier.

"Of the thousands of products that manufacturers announce each year and the hundreds that EDN reports about, a few hot products make our readers sit up and take notice," said Maury Wright, EDN editor in chief. "From chips to boards to software to test equipment, the 2003 Hot 100 are the products that we feel are sure winners."

"We are delighted that our single-ended current-sensing ICs were named an EDN Hot 100 Product of 2003," said Chong Tze Siong, vice president and general manager of Agilent's Isolation Products Division. "This award is a testament to the new product development effort that went into creating these industry best optocouplers."

The Agilent HCPL-7510 and HCPL-7520 single-ended, optically isolated, linear current-sensing ICs are optocouplers specifically designed for low-power electronic-controlled motor drive current-sensing applications. These applications include low-power inverter current-sensing, motor phase and rail current sensing, and general-purpose analog signal isolation.

The Agilent HCPL-7510 and HCPL-7520 incorporate advanced sigma-delta analog-to-digital converter technology to provide accurate linear current-sensing performance with single-ended output. Key product specifications include 15 kV/microsecond common-mode rejection at 1000V common-mode, 100 kHz bandwidth, single-ended output, 0.06 percent nonlinearity, and a gain tolerance of +/- 3 percent (HCPL-7510) or +/- 5 percent (HCPL-7520). These features ensure true isolation, high noise immunity, and the stability needed to accurately monitor motor current in noisy motor control environments. The devices are supplied in a compact, auto-insertable 8-pin DIP package to reduce board space, insertion time and cost.
