IDT Enables Sanxing, a Leading Energy Meter Provider, to Address Renewable Energy Measurement Needs and Simplify Manufacturing

SAN JOSE, Calif., – Integrated Device Technology, Inc. (IDT ®; NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced that the IDT single-phase energy metering IC has been selected by Ningbo Sanxing Electric Co., Ltd., a leading electricity meter manufacturer, for use in its single-phase smart energy meter. Sanxing selected the IDT energy metering IC because it provides the widest dynamic range of all high-accuracy solutions on the market.

The IDT90E24 belongs to a family of high-performance energy metering ICs for single-phase two-wire, single-phase three-wire or electricity meters with anti-tampering mode. It offers the industry’s widest dynamic range of 5000:1, enabling accurate measurement of several tens of kilowatts down to just a few watts. The device is ideal for measuring large power consumption during peak load hours, and also for measuring small amounts of generated power from renewable sources such as solar and wind during off-peak hours; all within a single smart energy meter.
