Following on from the release of DCL34xx0B Series of quad-channel standard digital isolators, the addition of these new products brings Toshiba’s lineup of low-power-consumption standard digital isolators for industrial equipment to ten products, including six in the DCL34xx0B Series. This expands channel-count options and contributes to improved design flexibility.Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

Please try againIn industrial equipment, such as programmable logic controllers (PLCs), actuators and inverters, it is crucial to prevent equipment failures, the propagation of abnormalities, and malfunctions caused by noise, which increases with higher-speed device operation. All these issues are addressed by electrical isolation that transmits signals between circuits operating at different potentials, such as high and low voltage, which is driving demand for safe, highly reliable isolation devices that maintain stable operation in noisy environments. Alongside superior reliability, and as equipment continues to become more compact, isolation devices are also, more than ever, required to offer smaller sizes, plus a longer service life. In addition, reducing overall system power consumption is at the heart of achieving carbon neutrality, and low-power operation has become an increasingly important requirement in electronics, including isolation devices.All four new products use Toshiba’s proprietary magnetic coupling isolation transmission technology[3] to meet market requirements for high reliability and long service life. They also incorporate a new Toshiba circuit technology in the isolation signal transmission section that allows them to achieve low power consumption of 0.2mA per channel[1] (typ.) at 1Mbps, while supporting data transmission at speeds of up to 25Mbps (max). These characteristics contribute to stable equipment operation and lower power consumption.The new products are rated for an isolation voltage of 3000Vrms (min) and operate over a wide temperature range of -40 to 125°C, and a wide supply voltage range of 2.25 to 5.5V. The adoption of an industry-standard SOIC8-N package meets demand for more compact equipment designs.DCL32xx00 Series products are suitable for I/O interface applications. The DCL320C00 and DCL320D00, configured with two channels, support unidirectional digital signal transmission, such as I2C communications[4]. DCL321C00 and DCL321D00, configured with one forward channel and one reverse channel, support bidirectional digital signal transmission, such as UART communications[5]. This enables flexible product selection according to application requirements.This advertisement has not loaded yet, but your article continues below.Toshiba offers ” DCL54xx01A Series” and ” DCL52xx00 Series” as standard digital isolators for industrial equipment supporting high‑speed data communications, and ” DCM34xx01 Series” and ” DCM32xx00 Series” as standard digital isolators for automotive applications, allowing customers to select products that meet application requirements.Toshiba will contribute to the realization of carbon neutrality by continuing to expand its lineup of digital isolators for industrial and automotive equipment, broadening the channel count and package options, and pursuing performance improvements. Along with photocouplers that provide optical isolation, Toshiba will provide a lineup of high‑quality isolation devices that support stable operation in communications and control systems requiring electrical isolation.Notes: [1] Calculated using 1Mbps operating current value, derived from (IDD1+IDD2) divided by two channels.
