Toshiba Releases Digital Isolators that Contribute to Stable HighSpeed Isolated Data Transmissions in Industrial Applications

0

Kawasaki, Japan:

Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched high-speed quad-channel digital isolators, the “DCL54xx01 Series,” that feature 100kV/μs (min) of high common mode transient immunity (CMTI) and a 150Mbps high-speed data rate. Volume shipments of the six products in the series start today.

Ensuring the safety and reliability of factory automation equipment requires isolation devices that ensure insulation and prevent noise propagation. Toshiba is now offering digital isolators as a solution that address requirements for higher speed and multi-channel signal communications and high CMTI.

The new products use Toshiba’s proprietary magnetic coupling type insulated transmission method to deliver a high CMTI of 100kV/μs (min) [1]. This realizes high tolerance of electrical noise between input/output in isolated signal communications, and also contributes to stable control signal transmission and equipment operation. With their low pulse width distortion of 0.8ns (typ.) [2] and high-speed data rate of 150Mbps (max), the digital isolators are suitable for multi-channel high-speed communications applications such as I/O interfaces with SPI communications.

Toshiba has provided its customers with photocouplers, isolation devices that ensure insulation through optical coupling, for 50 years now. Going forward, in addition to photocouplers, the company will expand its lineup of high-speed quad-channel digital isolators, plus the number of channels and packages, and offer high-quality insulation devices that support the reliable, real-time data transmission required for industrial equipment control.

Applications

    • Industrial automation systems (I/O interfaces, programmable logic controllers, etc.)
    • Motor control
    • Inverters

Features

    • High common mode transient immunity: CMTI=100kV/μs (min)
    • high-speed data rate: tbps=150Mbps (max)
    • Low pulse width distortion: PWD=0.8ns (typ.) (VDD1=VDD2=5V)
    • Quad-channel:

      Four channel of forward directions and zero channel of reverse direction

      Three channel of forward directions and one channel of reverse direction

Notes:

[1] Test condition: VI= VDD or 0V, VCM=1500V, Ta=25°C

[2] Test condition: VDD1=VDD2=5V, Ta=25°C
